Perhaps I should have mentioned that I don't have POTS, but the blood pooling/autonomic issues seem to overlap with the POTS folks on here. During much of my twenties I had chronic anxiety and my heart would constantly beat fast and I had a host of anxiety related issues (IBS, depression, insomnia, etc). However, as tough as it was I was highly functioning and those issues resolved over time. I could write a whole story just on this battle. I am wondering if my nervous system was just doomed to fail from the start :/ I had many blood tests, but all tested negative. All of the major viruses, bacteria infections, STDs, autoimmune issues, etc. In fact, I still have not gotten EBV and I am about to turn 31. I know for certain I caught a virus because a few people I know all had the same mono-type of illness. They recovered in a couple weeks. I nearly recovered over the same period of time but then one day I woke up feeling like I got hit by a car and that's when my issues really kicked into high gear. A couple Docs suggested CFS. The autonomic issues led me to my neurologist who said it was a "super-infection". This is when multiple strands of the same virus throw the immune system into disarray. He said 1 - 2 years for a full recovery. I never heard of such a thing, but this guy definitely knows his stuff so I just accepted it. I also have flushing in my nose and ears, which can be embarrassing. Also my chest. No real pain there tho. My hands get very red, but do not hurt. I think the only reason the feet really hurt is because I walk on them when they are engorged in blood. Elevating helps, and I prefer to cool with a fan than with water. Overall everything is just so temperature sensitive on the hot AND cold side since this all started. It's easy to get really scared about all of these conditions. I think it's important to listen to the doctors and to try not to get into too many hypothetical thought patterns. Everyone's case is different so speculating on prognosis can be dangerous. I admit tho that sometimes it's hard not to let your mind wander. TCP - did your ME/CFS improve over time? Did the autonomic issues subside with this? Sounds like you are struggling with some neuropathy. I am glad you are finding some relief. Barb - what were the symptoms of your virus? Was it particularly nasty? Some of my symptoms were really strange.
