and T4 of 4 (range 9-18).My latest test results in mid Feb indicated that I was now within range TSH of 0.2 (range 0.1-0.5) and T4 of 15 (range 9-18). However, the symptoms have slowly been returning and now if I do not take ibuprofen, co-codamol and amitryptiline then I am getting the chronic muscle ache. The brain fog and slurred words are also returning and I am constipated and very tired - falling asleep at 8.00pm. I have been taking levo at 150mcg in the morning (half hr before breakfast) and standard vitamin and iron supplement in the evening. I have an appt at the drs this afternoon and want to know if I should ask him to treat the symptoms regardless of the last test result as I am not due my next blood tests until mid April. I am concerned that I have had no other tests and could be lacking in something stopping the levo working or should I ask him to up the dose for a trial period to see if symptoms reduce.
