I have had a M.R.I it showed I have Tendinitis pain in my arm. I have been treating this with ice. I also have Calcium in my shoulder. Can that cause the pain and Tendinitis in my arm? I have had Fibromyalgia for many years. I m 87 years young, I live in assisted living, because of the Fibro. I get around very well, I do a lot of walking. Sincerely Beryl Small.
