I developed sharp shoulder pain 4 nights ago after having been in a recliner with my arms up over my head. When I took them down is when the pain started. I had an appt. with my thyroid doc the next day and he just said it was most likely tendonitis, take ibuprofen and apply cold. I've been doing that but my arm seems worse as time goes on. Is it normal for me to have my arm just "glued" in L shape against my body? It still hurts when resting it like this, but is the least hurting position. I can't just dangle it, I can't lift it up--if I try, the sharp pain is bad. When just resting, my whole upper arm aches. I usually use my opposite arm to lift or move my hurting arm. Does all of this sound normal for tendonitis? Many years ago I would shoot hoops with my kids and hurt my shoulder, so that I couldn't lift it overhead without pain. It finally went away after a year or so(I just didn't shoot hoops anymore!). But when I had that, at least my arm didn't hurt when it was down and being used. This new injury just seems so much worse.
