Hi, I was told by my GP to reduce my Levo from 125mg to !00mg as my TSH levels were low on two occasions. I feel dreadful today croaky voice, muscle ache and have been in bed all afternoon as soooooo tired. I ended up in hospital three weeks ago as I had a funny turn, vision cloudy and thought I was going to black out plus tingling all over face. I have not felt well since then and wonder if it could have been thyroid related. I am starting to consider lyme disease but not sure if I am on the right track. Anyone got any advice as the way I feel I am going to have to give up work as I feel too ill to carry on.
