Unfortunately, I started having the circulatory problems (extreme, almost constant light-headedness) a few weeks ago. And my current GP believes CFS is best treated with CBT. I've signed up with a real ME/CFS clinic, but it will probably be at least a couple months before I have an intake appointment. And that will mostly just get me a diagnosis ... I don't think I can schedule appointments a week in advance, etc, if a new symptom flares up or anything. So how do I go to my GP to get help with the light-headedness, since she doesn't believe CFS is a physical condition? And how do I explain that the problem is probably circulatory, since it's the same problem nearly everyone else with CFS has? I was hoping this was a temporary thing and I could wait it out, eat salt, and drink water, but it's getting worse if anything.
