The shoulder is a complex body system tasked with moving the arms.  It is comprised of the shoulder  blade (scapula), collar bone (clavicle), humeral head (nearest end of the upper arm bone) and the breast bone (sternum), and associated muscles, ligaments and tendons that hold it together and move it.

When a patient complains of shoulder pain, it could mean pain in any of these areas.  The doctor has to ask the patient to point to the precise area of pain, and ask the patient to move the arm and shoulder to get a better idea of what is causing the pain.

Today we’ll talk about general ache in the glenohumeral joint, comprised of the humeral head and glenoid fossa of the scapula (the shallow cup-shaped  surface of the scapula).

First of all, realize that the glenohumeral joint has the widest range of motion of all the joints in the body.  You can do all sorts of movements with your shoulder joint– raise your arm from the side, the front, the back; transcribe small and large circles, hug yourself, spread your arms far apart; throw a football, and throw an underhand pitch– that’s a lot of movement, compared to, say, the knee.  In order to accomplish such a wide range of motion, there has to be a lot of moving parts (ligament and tendon attachments).  When you have a lot of moving parts, there is a greater chance of something breaking down.  And this is why shoulder problems are quite common in people.

A general ache in the glenohumeral joint can be the result of sleeping on your shoulder; an old injury, or simply over-using it.  Tendons that slide over bony surfaces to move the shoulder joint in its many directions may be pinched in the narrow confines of the glenohumeral joint.  It makes the shoulder feel stiff and achey.

NOTE:  feeling a very deep and sharp, focal pain in the glenohumeral joint that is worse with a particular angle of arm movement is a different presentation and is not what we’re addressing here.

This is about general achiness and stiffness that does not cause any weakness or disability of the shoulder.  If you have more of a sharp pain that doesn’t go away with rest or medications, refrain from doing the following exercise until you see a doctor who can properly diagnose your problem.

TREATMENT:

You will be doing gentle stretches to get the shoulder joint moving, eventually without the achey and stiff feeling.

First, let’s assume it’s your right shoulder that has the problem.  Stand with your left foot about a foot forward of your right foot.  Bend at the waist but keep your lower back straight, and rest your left hand on your left knee.

Let your right arm hang limp straight down.  Sway your body in circles to get your limp right arm to transcribe a clockwise circle shape.  Try not to use your right shoulder muscles themselves, let the rocking movement move the shoulder.  Do ten circles, then reverse directions. Do 5-6 times a day.  If you do it correctly, the mere weight of your right arm will traction the glenohumeral joint (slightly pull apart the surfaces) and the rotation movement will stretch the ligaments in all directions.

Try adding a small weight, in increments throughout the week (do not exceed ten pounds max) to increase the amount of traction.  You should feel a gradual loosening of the shoulder joint, and less pain.  Avoid sleeping on the affected shoulder for a few weeks.

The other exercise is more challenging, so only do it if the pain has gone down considerably.  Take a bath towel and roll it length wise.  Grab one end with your right hand, and raise that hand (90 degree elbow bend, upper arm at level of shoulder).  Reach behind you with your left arm and grab the other end of the towel with your left hand.  Now, extend your right elbow back and forth as though you are drying your back with the towel.  Do for about a minute, and then switch hands.  Repeat.

As always, if any of these exercises cause an increase in pain, stop immediately.

What to Do if You Have a Bulging Disk

Lower back pain presents in a range of severity depending on the structures generating the pain.

A simple sprain/strain can still cause extreme pain, swelling, and immobilization for a couple of days but should completely resolve after a few weeks with proper care and rest.  Lumbar sprain/strains are associated with lifting something heavy, or even simply bending or twisting at the waist; weight lifting, sports injuries and trauma like a car accident.  By definition, they are limited to injury to the muscles, fascia, tendons and ligaments.  The pain is limited to the area of injury.

A lumbar disc bulge occurs when a disc “bulges” outwards due to weakness or injury.  A disc is a tough, fibrous ligament that holds the lumbar vertebrae together at the vertebral body.    The disc’s outer periphery, called the annulus, resembles a slice of an onion, with multiple rings of fibrous tissue encasing a jelly-like material called the nucleus pulposus.  While tough and strong, it allows movement of the individual vertebrae.

By definition, a disc bulge is still intact and has not ruptured (as opposed to a disc herniation or rupture).  The bulge represents a weakened area in the annulus that allows the nucleus to gravitate towards a section of the periphery, usually the posterior (rear-facing) edge, facing the spinal canal (where nerve tissue is present).  It can be a broad-based bulge, or a more focal bulge.  If it is greater than 5mm (measured from the edge of the vertebral body to the tip of the bulge) it is clinically significant.  Many people have disc bulges and have no back pain at all; in fact, it is normal for the discs to bulge slightly in the weight bearing position (standing).

The problem occurs when the bulge contacts nerve structures.  If large enough, they can contact the thecal sac (contains the spinal cord and cauda equina) by bulging backwards into the canal, and they can press on spinal nerve roots by bulging to the sides.  The spinal nerve roots branch out in pairs from either side and exit holes formed between adjacent vertebrae called vertebral foramen, or lateral canals.  A disc bulging to the posterior and side can narrow this opening and pinch the nerve root causing pain to travel down the buttock or leg, depending on which nerve root.

TREATMENT:

If your lower back pain is felt deep, and you can make it hurt more by bending your lower back backwards and to the side, you may have a disc bulge.  You may or may not have pain and/or numbness going down the buttock and leg (same side of the pain).  If it happened while lifting something heavy, the diagnosis is more likely.  If you have extreme, unchanging pain with more constant leg pain or paresthesias (numbness, tingling) that does not get better with ice and rest, you may have a disc rupture (also called prolapse) where the inner nucleus had broken through the annulus and is in the spinal canal or lateral canal.  If you have changes in your gait (walk) such as foot drop, weakness in your legs, difficulty walking upstairs, then the diagnosis of disc prolapse  is more probable.

Disc bulges can be managed with conservative treatment like home care, chiropractic, and physical therapy.  Disc prolapses should be evaluated by an orthopedic surgeon or neurosurgeon.  An MRI should be ordered to evaluate the extent of the injury.

If you suspect you have a disc bulge, take care not to aggravate it.  No heavy lifting, no jumping activities (basketball, badminton– anything where your feet leave the floor and land hard).

Discs usually bulge backwards (posterior), so do movements that encourage the bulge to move back to center.   Lie on your back and bring both knees to your chest (ok to use your arms to grab your knees while they are bent, and pull and hold to your chest).  This will put your lumbar spine in flexion, or a nice convex curl.  Your back contour should be like that of an egg, and you should be able to rock back and forth.  Maintain the pull, stretching your lower back into this curve.   Hold for 30 seconds, then slowly extend your legs on the floor and rest for 15 seconds (optional:  put a frozen ice gel pack covered with a kitchen towlette under your lower back during this exercise).  Repeat six times.  This will have the effect of creating separation between the posterior ends of the lumbar vertebrae, helping to reduce the bulge.

Next, stand and place your hands on your hips, and slowly arch your back backwards, putting your lumbar spine into extension— the opposite curvature as the previous exercise.  Bend back until you can’t anymore, but don’t over do it.  Hold this position for six seconds, then return to neutral.  Repeat eight times.  This will have the effect of bringing the posterior ends of the lumbar vertebrae closer together and pushing the nucleus back towards the center.

Do the above series of exercises three-four times a day for a week until the discomfort is gone.  At this point, you should focus on doing things to strengthen the disc.  Eating a wholesome, healthy diet with enough protein, fat and plant material will help; avoiding destructive activities like smoking, alcohol, and staying up late will enable optimum conditions for tissue healing.  Gradually start doing exercises that improve lower back muscle conditioning and coordination.

Getting a series of 6-8 chiropractic adjustments to the lumbar spine may also  be helpful in reducing your bulging disc.

How to Relieve Pain from Hot Peppers

Habanero pepper

Peppers contain a substance called capsaicin that gives them that hot sensation when exposed to thin membranes such as in the mouth, eyes, nose, and open wounds on the body.  The amount of capsaicin determines the “hotness” of the pepper.  Bell peppers are on the low end, while habanero peppers are on the high end.

Research shows that capsaicin, despite its fiery reputation can reduce inflammation.  There are now over the counter pain relief products that contain capsaicin, mostly topical applications.  The capsaicin creates a mild burning sensation on the skin, resulting in a counter-irritant effect that may temporarily relieve muscle pain.

Some people may apply too much of the product on their skin and suffer from a very uncomfortable burning area on their body that doesn’t go away with soap and water.  If you find yourself in this situation, here are some suggestions:

1.  Rub coconut oil over the area.   You can buy virgin coconut oil in most health food stores.  It is even better if it is in a  solidified state (below melting temperature).

2.  If it is a case where you ate a pepper, don’t try to wash it out with icewater; instead, gargle whole milk for 30 seconds; spit out.  Repeat three times.

You can experiment with other types of fats such as olive oil, lard, and butter.

Before handling very hot peppers in preparation for cooking (especially if you are going to slice them and expose the capsaicin) coat your hands in olive oil.

By all means, do not touch the eyes and nose during the handling, and even several minutes after you’ve handled very hot peppers and washed your hands, just in case.

What Can Be Done About Meniscal Tear?

Image via Wikipedia

The meniscus is a shallow bowl shaped piece of cartilage that is attached to the lower leg bone, or tibia.  There is a medial meniscus (inner half of knee) and a lateral meniscus (outer half of knee).

The end of the femur (upper leg) bone has two protuberances called the femoral condyles, which rest on top of the meniscii (plural).  In the standing position, the meniscii bear the full weight of the body above the knee.  They serve as a cushion and shock absorber and protect both of  the ends of the tibia and the femur.  The meniscus also guide the action of the femoral condyles as you bend and extend your knee.

The knee is obviously a highly utilized, weight bearing joint.  It has the largest suface contact area of any joint in the body as it has to bear most of the body’s weight and on top of that, absorb shock from walking, running and jumping.  It is held together by several strong ligaments, the primary being the anterior and posterior cruciate ligaments (ACL, PCL), the medial and lateral collateral ligaments (MCL, LCL), and the patellar tendons.  It is a synovial joint, which means it is totally encapsulated and lined with synovium, a specialized tissue that secretes synovial fluid to lubricate the joint.

The slightest alteration in the inner workings of the knee will lead to problems.  A common one is a meniscal tear.  The two basic types are a radial meniscal tear and a vertical meniscal tear.  A radial tear that expands forms what is called a “bucket handle” tear (3rd set in the below image- top and bottom).

types of meniscal tears

Meniscal tears are caused by excessive pounding forces to the knee, which weaken the meniscii over time.  Eventually a tiny tear forms, which grows in length as the individual continues to engage in the offensive activity (running on hard pavement, weight lifting, playing basketball, etc.), much like how a tiny crack in a car windshield grows into a long crack over time .  If a small piece breaks free, it floats inside the knee space, suspended in the synovial fluid.  Like a grain of sand in a watch, it interferes with the moving parts and can cause the knee to swell and become stiff..  Pain is felt deep inside the knee and is worse with prolonged standing and transitioning from sitting to standing.

Meniscal tears increase the chances of accelerated knee osteoarthritis, as “bone on bone” contact occurs between the ends of the femur and tibia.

TREATMENT:  Diagnosis is made with a knee MRI and arthroscopy.  Meniscal tears will most likely require arthroscopic surgery involving repair to the tear.  If you have a gradual onset of deep, focal knee pain accompanied by knee stiffness that doesn’t go away, see your doctor.

Prevention, as always, is the key.  I advise against sports that involve consistent and prolonged pounding forces to the knee.  This includes long distance running and frequent hard court basketball that involves jumping.  Consider doing functional exercises that combine cardio and strength instead.

Most leg exercises will strengthen the knee.  Do mostly closed kinetic chain exercises where the foot is immobilized.  This includes squats and lunges.

Intermittent jumping exercises are ok as long as they are controlled and are not the focus of an exercise session.  Power jumps and related plyometric exercises fall into this category.

Most meniscal tears grow too large to heal on their own by the time the patient seeks medical help.  This is why surgery is the only option.  The surgeon stitches together the tear, but thanks to the forces the knee has to endure, the tear often returns.

Some patients do not get surgery, and let the tear become chronic.  When it’s chronic, there is less acute pain, and more of a broad, dull pain in the knee.  In this scenario, the knee joint will experience accelerated degeneration, leading to knee osteoarthritis.  Eventually in the later years, knee replacement surgery is needed.

I made a general Knee Pain Rehab instruction video that includes things one can do to help deal with early stage knee pain.

How to manage lower back strain

Low back pain is said to be the most common cause of lost work days, after the common cold.  Most everyone has experienced an episode of lower back pain at some point in their life; millions suffer from chronic (ongoing; unending) lower back pain of some form.

The low back, or lumbar spine, is comprised of the last five (5) vertebrae in the spine.  These vertebrae are the largest as they support most of the body’s torso weight.  Like the cervical spine; i.e. neck (the first 7 bones of the spine), there are no rib attachments in the lumbar spine to limit movement, making the lumbar spine more moveable than the thoracic spine (torso), but less flexible than the cervical spine due to its larger, heavier vertebrae.

This unique lumbar spine design offers advantages and disadvantges.  The obvious advantage is flexibility–you can bend (flex) your low back forward, backward, sideways, and can rotate it a few degrees to either side.  The disadvantage is  that with more movement, there are more opportunities to stress the joints of the lumbar spine (more moving parts) and therefore more chance of injury and pain.  This includes potential injury/ trauma to the surrounding ligaments, joint capsules, cartilage lining the small joint surfaces; small facet joints, intervertebral discs, and the lumbar vertebrae themselves.

Therefore, low back pain can originate in one of several structures in the lower back:

  • the discs (strong fibro-cartilage ligaments that hold vertebrae together)
  • the facet joints (the “rear” joints of a vertebra, opposite the vertebral
    Lumbar vertebra.

    bodies)

  • the pars– the small extensions of bone to either side of the vertebrae that form the upper and lower borders of the intervertebral foramen, and end in the lumbar facet joints
  • the surrounding muscles
  • the surrounding fascia (muscle covering)
  • the nerve roots inside the spinal canal
  • the vertebrae itself (compression fractures; vertebral end-plate fractures)

Today we’ll address lower back pain due to muscle and fascia strain.   I’ll refer to this a low back or lumbar strain.   This is a common cause of lower back pain and is more manageable than pain due to deeper spinal structures.

In the many cases of lower back strain that I’ve treated over the years, the patient describes a sudden onset of pain after bending at the waist reaching for something.  In other cases, the pain starts a day after doing something like weight lifting, running or rock climbing.

Medically speaking,  a muscle sprain-strain occurs when muscle fibers tear during contraction and subsequently release inflammation.

The convention for naming soft tissue injuries is that strain refers to injury to a muscle and tendon while sprain refers to injury to ligaments, which connect bone to bone.   Since muscles, ligaments and tendons typically get injured all at once in a typical injury due to their anatomical proximity to one another, doctors refer to these types of injuries as sprain-strain injuries.

Sprain-strain severity is described as Grade I, Grade II and Grade III, with Grade III being the most severe and refers to complete rupture of a tendon or ligament.  Most lumbar strains are Grade I and II.

Inflammation is meant to contain/ quarantine an injury and is actually an important process in the healing phase (tissue regeneration).  The problem is that it releases chemicals that irritate nerves and surrounding tissues, and stiffens adjacent muscles and joints.  The inflammatory response can “overshoot” causing the patient to needlessly suffer.

If you go to your doctor complaining of lower back strain, and tests do not indicate damage to deeper structures (discs, facet joints, nerve roots, bone) then you will most likely be prescribed pain blockers (usually NSAIDs- non-steroidal anti-inflammatories), rest, and ice.  Your doctor will likely put you on “temporary disability” which means no heavy lifting,  bending at the waist, and other activities that put stress on the lower back.  Sometimes muscle relaxants are prescribed, if there are complaints of spasm and stiffness.  You will be told that it should resolve on its own, and most cases do.

TREATMENT:

At first onset of straining your back, apply ice for 20 minutes every two hours of the waking day.   The easiest way in my opinion is to get a large freezer ziplock back, fill a third of it with ice cubes, put about a cup of water in the back and zip it closed (get as much air out as possible before closing shut).

Lie down so that your exposed (no clothing) lower back is directly on top of the bag.  Bend your knees or put a pillow under them for comfort.   This flattens the lower back and allows it to make good contact with the icepack. (Optional:  put a neck roll under your neck for comfort).  Do this for 1-2 days.

On the second day, you can introduce gentle stretches while you ice.  After your 20 minutes of icing, try lifting your knees to your chest, pulling them gently towards you with your hands.  Hold for 5 seconds; repeat five times.  Then, keeping your feet together (you are still lying on your back), knees bent, let the knees fall to the right side, gently twisting the lower back; reverse sides.  Do five times to each side.  What these movements do is orient any scar tissue that develops, in the direction of contraction.

On the third day, assuming pain is still present, you can try using heat.  I recommend an infrared lamp.  This is radiant heat that penetrates deeper than a hotpack.

If you need to get pain free even sooner, I suggest using the 120 LED (Light Emitting Diode) wrap.  This popular home therapy device used red light therapy + infrared heat, which goes beyond simply blood circulation increase.  The red light diodes inhibit inflammation and increase cellular metabolism (energy production, waste removal) which means speedier tissue healing.

After a week, your lower back strain should be 60-90% better.   If it is only 25% or so improved after a week, the injury is likely worse than originally thought; and deeper soft tissues may be involved.  In this case, consider using Pulsed EMF to further enhance tissue healing.

Last thought:  I believe that if someone strains his lower back by simply bending forward, it indicates that the back muscles, and probably core/abdominal muscles need better conditioning.  It’s not all about strength, it’s also muscle coordination in response to varying loads; for example, picking up a piece of heavy luggage.  Those with excellent muscle coordination (there are five major muscle groups that have to work together to move the lower back) are less likely to injure their backs like this.  Interestingly, research shows that osteoarthritis, or degenerative joint disease in the lumbar spine, is related to poor lower back muscle coordination.  And it makes sense– your muscles move and support your lumbar spine.  Poor support and coordination between muscles (erector spinae group, abdominals, etc.) can cause your spinal joints to bear more stress than normal during every day movements.

So, the best strategy is to prevent getting lower back strain by strengthening AND conditioning (improve coordination of) your lower back muscles by doing functional exercises.
