I have to go to the doctor for a physical, so I will probly ask him this then, but anyway...
I am a cross country runner that probably runs an average of about 4-5 miles a day. However, after about 3 or 4 miles, my vision goes blurry and my head starts to feel funny. sometimes my body will even go completely numb. also, it seems as if I have no realization to any pain, heat, thirst, etc.
is this normal? if it is or isn't, could you possibly explain?
