My TSH was 4.8 and so my doctor started me on 100mcg. I have been taking them for about 5 weeks but actually feel worse. I feel breathless, pain in my side has started up again, I am more constipated and my IBS has flared up. And the biggest problem - I have put more weight on. I have therefore stopped taking the meds but I do not know what to do next. Any help would be appreciated.
