I am experiencing what i think is exercise induced hyper tension. after exercise i start getting tunnel vision, nausea, and hearing loss till i stop. ?

A few possibilities: If you're otherwise healthy with no major medical issues and you don't take any medication, you may actually be getting hypotensive (low BP). are you drinking enough fluids? do you have heavy periods? are you over-doing your exercise program?

Exercise: Tunnel vision and hearing loss could be a sign of loss of oxygen to your brain. Do you get headaches? Do you have any history of drug use? This needs to be evaluated ASAP. Would not exercise and definitely not exercise to the point those symptoms appear until you see an MD.
