I am having the same problem, only I haven't been on any thyroid meds for 3 months and am still having episodes of hyper--racing heart, anxiety, shaky, freezing cold and frequent BM's. Last night was one of those episodes. I took my BP meds and they helped with the racing heart and high blood pressure (that I don't normally have) but I still couldn't sleep all night! I am shaky and so anxious. My endo wants me to have a TT because he's tried everything else and nothing seems to work. I can not tolerate any thyroid meds since Feb. of 2013.
I've had a RAI uptake and thyroid scan which did not show graves...just two small nodules (neither hot nor cold) and only mildly swollen thyroid. I've had Hashi's since Dec. 2004
I want to have the surgery because I am so debilitated with these symptoms my life has come to a halt. The only thing is I'm afraid I won't feel any better as some people have had the TT and still have issues.
Anyone have any thoughts? I'm beginning to feel desperate
