I'm just wondering if anyone has an experience similar to this. I have a variety of symptoms. One of the most troubling is some neuropathy that has developed in my right foot. I also feel weakness in my right leg. Today, I drove about 2.5 hours in 80 degree temperatures (in fact I was driving to meet with a TMS physician). Not terribly hot but quite warm outside. On the way home, I noticed that my right leg and right foot were particularly symptomatic. More numbness and more of an odd sensation in my leg. This isn't new. I've encountered this before--particularly while driving in warm or hot weather (with windows open). I'm just wondering how warm and hot temperatures could prompt this reaction. I use a sauna at the gym fairly often and, for some reason, this reaction does not occur there. The sauna is much hotter, although it is for a much shorter period of time. These sorts of reactions always increase my anxiety and fear. I often start thinking about the possibility of something neurological going on--even though extensive testing has produced normal results.
