Hey, This is my first post, but I've been using the board for awhile now - mostly to confirm that other people have had whatever issue is bothering me at the time. I had been doing a good bit better (able to do some school work, a little exercise, etc.) but then hit a bad spell. Started getting pretty bad headaches at the back of the head and nauseau, neither of which I had had before. They aren't nearly so bad now, but still come back at times - I've noticed that mental exertion will bring them on, I think standing has, and yesterday I was fine until I laid down for a nap (but shouldn't that have the reverse effects of standing?). At the same time, several of my older symptoms came back: lightheaded on standing more often, more noticeable pooling in feet, muscles get sore very easily, trouble staying asleep, and sometimes a burning sensation in skin, usually on my back. Since it looks like plenty of dysautonomics get the headaches and nauseau and since the other blood flow related issues came back at the same time, it seems safe to say that the blood pressure stuff is the cause of the new symptoms too (too little blood to the head, I assume. too little to the gut?). But it's discouraging to get the old symptoms, much more so with these newer, more bothersome ones. So my question is what might have made the blood flow worse? I did a bit more school work during my good phase than I probably should have, but could that have so thrown my system out of whack that it caused all this for 2 weeks now? Or is there something else that might have done it? Or is this kind of worsening common and unexplainable? thanks alot, steve Oh, in case meds matter: taking Nasonex and Singulair for allergies (which I never had - or noticed - before the dysautonomia, I think I'll have to post about that too and adderall. I did up the adderall to 20 mg around when this setback began, but on days that I go back to 10 I don't notice any difference in symptoms.
