February 27, 2013 had sudden flushing that I literally felt start in my mid abdomen and felt it rise to the top of my head. Very red neck, face, and ears assoc with a very hot sensation. Even the whites of my eyes were red! It was transient. Next day had heart racing. Went to ER and had work up along with cardiac stress echo and other labs that were negative. Continue, for over one year, to have tingling in abdomen, back and neck with palpitations that are controlled with atenolol. Four doctors have seen me and tell me it s most likely thyroid as I have hair loss, consitpation, cold and heat intolerance and tiredness/lack of energy. Seen an Endocrinologist on Monday and he denies it could be thyroid chucking it up to perimenopause.
