Hi, I am diagnosed with hypothyriod and have been on 125mg levothyroxine for a number of years, I feel really old stiff, tired aching joints and muscles, sick and also get very dizzy if I move my head forward and side to side. my advise has been anti depressants which I dont like as they make me feel like im walking through cement.....really hard to function. my levels are..TSH 0.04, freeT4 21.2, freeT3 5.6, bilirubin 2, albumin 43, heamoglobin 11.7, white 4.4, mean cell 84.1,mc heamoglobin28. haematocrit 0.343. while all my readings are normal or border line, why do i feel so bad, i cant keep up with life......it is so sad, and painfull. Thank you.
