Hi, I have had Palmar Hyperhidrosis and underwent Sympathectomy in Febr.2007. It turned my life upside down. I got all the possible side-effects (I do not mean all the side-effects disclosed by the surgeons who offer the surgery, I mean all the side-effects that are described in the medical journals by doctors who investigate the effect of sympathectomy. And there are many). I have a long and very similar list of symptoms as you, and not sure if it will help in any way, but there are many on other forums who have similar symptoms as you and I after this surgery. I had a T2 cut, and it significantly affected my heart rate (bradycardia and abnormal beats, chronotropic incompetence - 70%), disabled thermoregulation, Hypothermia and hyperthermia on different parts of the body - at the same time, disturbed circulation, dyspnea, etc etc) The last diagnosis I had was dysautonomia, but nobody was able to address my condition and ended up being handed from specialist to specialist - at a great cost. That is why I joined the forum, because I am hoping that I will be able to glean enough informaiton form here that will allow me to deal with at least some of my symptoms. As to complicate my situation, I am also trying to deal with enormous grief and anger (rage), as all these symptoms/effects of sympathectomy have been described over and over in the medical journals, but the doctor choose not to inform me. I find that very difficult to deal with. My GP, and several specialist - not performing the procedure - I saw after were familiar with the consequences, so there is no excuse for the operating surgeon. It is a destructive surgery which indeed has the capacity to surgically induce dysautonomia.
