Request TSH, FT3 and FT4 tests. these would be a good starting point to see what your thyroid hormone levels are.
Low thyroid can cause pain and poor exercise tolerance as well as poor memory.
what test would be good to request from my doctor? my level is 4005 tpo i am totally exhausted could it be caused by possible hashimoto disease? I am also in terrible pain and can not walk very far. my memory is terrible.
Would correlate with TSH, but appears you have autoimmune thyroid disease (most commonly, Hashimoto's).
