3 years ago, I was putting heavy luggage into a car... the tuff guy in me, I was throwing those around... next thing, I come back inside the house, my right arm was in so much pain it wasn't funny.. for weeks after I could barely turn the key to start my car... I went to see my chiropractor for advice, he said it felt like a bursitis.. He treated me with a massage and somekind of an ultra sound device which heated up the area.. I did a half dozen treatments and alot of glucosamine.. It went away... I think I also stopped training my shoulders as hard as I used to.. but that arm has never bothered me again..
Now it's my other shoulder which is a little painfull, especially on chest and biceps days..
I'm gonna stick to dips, incline bench and crossovers for the next few months and see how it goes.. Anybody's input would be much welcomed...
