I am 19 years old, and keep having the same headache. It starts and gets bad and makes me dizzy and then goes away and comes back. Light intensifies the headache. Today it got so bad that i started sweating and then started freezing. It seems to be when i am active it gets the worst, like when i am at work. Or when i am even on the computer the light hurts my eyes. But other times when i am active it is fine. I dont know what to do. The dizziness is getting worst each time and it makes me feel very nauses please help!!!
