Hi, I was diagnosed hyperthyroid ? Cause last November. I have taken carbimazole on two separate occasions. The first time it was stopped after developing violent diarrhoea and high temperature. 2nd attempt on a lower dosage caused yet another fever although no diarrhoea. My Endo today wants me to restart it yet again but I am obviously reluctant, he says the reaction is not the carbimazole !! I really am at a loss what to do now. He has also reduced my propranolol for the palpitations. I feel he doesn't want to help me at all. Any suggestions?
