I m a 44 year old male, six foot, 186 lbs, who works out everyday with free weights and cardio. I m the type of weight lifting enthusiast who works opposing muscle groups equally striving for symmetry in strength and size. For the most part I eat very healthy including fresh squeezed juice daily. For the last month I ve noticed a pea sized bump on, which I believe to be, my coratoid process. The pain has a soreness to it perhaps resembling an arthritic pain and has become progressively more noticeable. It is located on my left shoulder and hurts more if I lay on that side. When I tighten the skin in that area it becomes very obvious in it s shape. I was going to get it checked out later on today and as you can imagine am very concerned about it. Any thoughts?

Coraco-acromial ligament injury? OA of the coraco-acromial joint. But other causes need to be ruled out like ? Gout ? Rh. Arthritis.
