ever since I had to have a complete thyroidectomy in June 2009. I have been prescribed varying doses of Synthroid. It worked well for the first two years, or I just thought it did and thought most of my symptoms were due to thyroid removal. However, even my endocrinologist has listed quite a long list of problems I might experience on Synthroid, and I’m definitely starting to think that even though this isn’t specifically mentioned, Synthroid is responsible for the chronic joint pain I’ve been experiencing almost whole last year. It gotten so worse that I have an appointment with rheumatologist, thinking it’s arthritis, but what are the chances Synthroid is responsible for my chronic pain?
