This is my first time posting, i seem to have the same problem that many of you have mentioned: my Left - Pectoral muscle as well as the left Triceps.

Today i went to the Physiotherapist, to my knowledge i thought it was a waste of money as she was touching my shoulder and neck totally not paying attention to the serious problem of the left pectoral as it clearly became much smaller then the right.

Her Diagnosis: Wikipedia reference-linkRotator Cuff ( that's right ) Pinched nerve ( as many of you mentionned ).

i am quite flexible and double jointed at the shoulders but my left shoulder makes a small click as my arm is rotated towards the top and it's believed that due to BAD POSTURE from either; sleepy badly, playing computer, stopping activities that use to b done. I'm glad to hear that others have seemed to recover some strenght.

6" 200 lbs previous bench 280 lbs
current bench a shameful 120 lbs (with difficulties)

i aswell have seem a major drop in left Triceps and i believe the nerve damage is linked.

Physio therapy suggested is working the rotator cuff
using adjustable cables start with a small weight at elbow height and pull from the exterior to the interior and place a towel between the elbow and torso make sure the movement should not move in the elbow but just to focus on the rotator cuff. I'll post back in a few days with results of workout and keep thread alive.

Also when in normal stance your shoulders should not be facing forward but more like pulled back which she explained is more natural and more room for the nerves if you find yourself having shoulders that are more infront that could b the start of your problem reply back thx.

There is hope
