Hello Dr . My name is Sherrie and 20 mths ago I had my Thryoid out and I am on Thyroxine for life . My problem is we can not get it balanced .I had chest pain yesterday and felt terrible , but after all the right heart tests done by my local hospital , my heart was clear , My thyroid levels dropped to 0.03 six weeks ago and I had a shocking week of complete weakness , nausea , vomiting , and I slept for two days .I haven't felt right since , At the moment I an on 150gm and feel tied again . When I felt at my best my levels were 16 , dose it really matter what your levels are if everything feels fine ?
