Hi all, I have had POIS for 18 years but have never been brave enough to visit my doctor about it. I also have CFS/ME. My POIS symptoms are similar to what most of you have described, but sometimes, if I've had a lot of stress as well, I have severe nerve pain as part of my  symptoms. It is so bad that I cannot stand light or noise and just want to scream. This nerve pain feels like I am plugged into an electric sockets it's so severe. Also, I look physically different: very pale; swollen, puffy face; neck pulled tight back. Does anyone else have these severe symptoms? Does anyone know of any medications that help? x
