I have unexplained pain and limited range of motion in both upper arms. It started with my left shoulder and I was diagnosed with frozen shoulder, went to PT with no relief. Recently the same symptoms have appeared in my right arm with the same limited range of motion. I can't raise my hands fully over my head nor put them behind my back. I saw my primary last week for physical and all blood work has come back normal. Doc is stumped. Says I probably need lots of PT and exercise and that it could take years to get better! I am 46 and this is very frustrating. Also of issue and probably not related is I have right knee pain and can't bend knee fully (It feels very similar to meniscus injury I had on other knee which was surgically repaired in 2012.) At this point I am looking for diagnosis but don't know what kind of specialist to make appointment with. I feel I have exhausted my primary care's knowledge/expertise...so I have turned to the internet to help guide me as to the next course of action!
