Im 16 and im a dancer.  I have been a dancer for almost 13 years.  Recently over these past 6 months, when I dance I get really dizzy to the point where i feel like im going to faint, sometimes my arms or hands get numb, and i feel really weak.  It has been concerning me because I dont know anyone else who gets like this and my dance teacher told me that maybe I should go get it checked out.  I dont eat meat except chicken and I dont eat eggs so she things that I may be low on protein.  I think this may have part in it but I think there is more to it but I dont know what it is! I have mentioned it to my doctor a few months ago and he said he was going to run blood tests but never did.  Does anyone else ever get this way? Am I the only one? What do you think the problem is? Please help!
