Been on Levothyroxine for eight years. My dose got increased to 100mg from 75mg. In february of this year I noticed the start of Tremors and Fasciculations on my left hand and calf. Checked my TSH in March and it was 4.0. The problem has got much worse over the months until in August I checked my TSH again and this time it was 6.48. My Doctor increased my dose to 125mg. Been on it now for 2 1/2 weeks and my Fasciculatons are worse. Blood test again after two weeks shows a TSH of 3.0, Free T3 4.9 and Free T4 of 12.5 all other tests were normal. I take my dose of 125mg last thing at night and the shakes from the fasciculations wake me up after 2/3 hours.
What can I do to minimise the side effects, what am I doing wrong?
