Brand new member here! (60-year old male!) I don't have any real answers, but I, myself, have hypothyroid, and I am currently experiencing my second bout of adhesive capsulitis. I'm not sure what the relationship is between thyroid issues and FS, but I sort of suspect that it might be related more to hypo- rather than hyperthyroid. I had it a few years ago in my right shoulder--it took me close to 2 years to recover from it. Now, my left shoulder is in the "freezing" stage, I thnk. It is, as lots of people know, a very distinct type of pain--I experience it as an intense tearing pain, as if all the attachments inside the shoulder are being ripped off whatever they are attached to! Sorry to be so graphic, but that's how painful it is. When I last had it, the orthopedic specialist gave me one shot in the shoulder and prescribed physical therapy--which, in my opinion, was valuable only to teach me how to exercise at home. In this current bout, I am taking an herbal approach first--my physician, who is an M.D. and also trained in TCM, has prescribed turmeric and bromelain (I cannot take the bromelain, due to GI upset). I cannot say that the turmeric is helping yet, but the doctor said it is slow to act--maybe 6-8 weeks. Yep, frozen shoulder is a real stinker!
