Hi, I am not sure if this is something common, or normal, because I have not heard anyone else mention they have this happen, or see them look how I probably do when this happens...
Ever since I was young, I always have this problem where if I am standing, and stand still there(am not walking around), after a while, I will start to feel very sick to my stomach(very much like I am going to throw up), I feel kind of dizzy and nauseous...it's difficult to explain (as most feelings are I suppose). But it gets so bad I really feel like I'm going to collapse, and my forehead/face feels kind of hot...I end up inevitably sitting down at that point, as it's such a *horrible* feeling...
I mentioned this to my parents at one point when I was in middle school, about 8th grade if I recall correctly. They dismissed it as "you to get some exercise". While it's true, I don't get much exercise (although I am very skinny), there are other kids that are the same, I don't see them having these problems...
I can remember very clearly, a point in time when I was in about 2nd, 3rd, or 4th grade....every student was made to stand up for a long time (no idea how long in time..), on a stage with hot stage lights beaming down upon us. I had this *same* exact feeling occur. When we were practicing, after a while of singing (it was some mandatory-chorus thing), I would begin to feel very sick, to the point where if I didn't sit down, like I said..I'm quite sure I would have just passed out. So I sat down...I begin to feel a lot better(it isn't fully gone in an instant..just a lot better in an instant) after I sit down...
It's also worth noting I guess, that if I do not eat when I am hungry, I will usually end up feeling quite nauseous when I have to do something, like spend many hours digging holes, or something... (I think it's somewhat the same feeling too).
I don't know what this is, or if it is anything unnormal...I really wish I knew what it was, so I could hopefully fix it, as standing up for a while and not walking around, and listening to someone talk for example (30 minutes I guess, maybe more?), will make me feel like this, and I end up looking like a wimp, or someone who doesn't care to what they have to say and wants to leave, just because I have to sit down....
I would really love for this to go away, but even if not, it would be wonderful if it could just be diagnosed (or dismissed as nothing), I think the part of uncertainty is definitely the worst...as I don't know what to tell people.. it would be great if I could say "I have (this) disease".
