Hi, I have been to my GP today for routine blood results to find my estrogen is low. I told her I was glad to see her as I had another panic attack last night. She is reducing my medication at the moment as My levo was too much and she was blaming panic attacks on the levo levels been too high. I was taking 150mg and for the last month I have been taking 125mg. I am still having palpitations and panic attacks (first time in my life) and wondering if the low estrogen and levo not been quite at the right level is causing this. I have booked to see an endo as I can not accept these issues, they are ruining my life. Have I done the right thing here? I don't want to waste the endo's time but need answers and fast. I can't tell you how awful these symptoms are. GP ran more bloods and talking about reducing levo even more, I think that could cause even more problems. Any ideas??
