I had my thryoid removed 6 years ago, 2 years ago, out of the blue I had a panic attack for no known reason, I went to the E.R., did not know what was going on, and the doctor told me I had to much medicine in me, I was taking Synthroid, with in the last two years, and several doctors, and switching to Cytomel, because I was told I could not convert Synthroid any longer, I still have trouble with anxiety for no know reason, although my numbers when they start to get better, I feel worse, when my numbers are off, I do not experience any anxiety!! I am so lost on what to do, I go to doctors hoping someone listens to me and not the blood results, it is so frustrating!! Anyone please give me some feed back, thank you.
