I had a partial thyrodectomy over 16 years ago and have been taking levothyroxine, but over the past few years my weight has rocketed. Lateley, I have days when I am thoroughly exhausted, very painful thigh and buttock muscles, pain in my wrist and hands and weakness in my hands. Also my hair has been thinning. I went to my GP for tests for hypo active thyroid, my results came back :- TSH level 0.33 and T4 13. My T3 level was not tested. My GP told me the results were normal/O.K. and is now sending me to reumatology after various other tests came back clear. I am not convinced, and would appreciate any input on my levels.
