My physical therapist told me today (June 9) that he thinks I have rotator cuff *tendinosis*, not tendinitis. Whereas tendinitis involves inflammation and is likely related to an acute injury, he says tendinosis is the result of repeated "mini-injuries" to the tendons and of cellular problems, including abnormalities in the collagen that makes up the tendons. (I found a very interesting web site about tendinosis, in case anybody is interested. I think it's the first one that shows up in a Google search on "tendinosis.") The upshot is that my PT says there isn't much more they can do for me, that I should just avoid the activities that seem to aggravate the pain and do gentle stretching and strenghthening exercises, than try for another referral to PT if things aren't better in a few months. I was wondering whether anybody else has ever heard of tendinosis. One interesting thing at the web site is that I recognized some terms I've seen mentioned on this board. Unfortunately, it seemed to me that aome things that were being recommended here for treating fibro would aggravate the tendinosis problems (and maybe the reverse). Just what I needed--*another* chronic condition! What a pain (quite literally)! --Laura R.M.
