I have been having migraines for about 4 years. In Dec of 2006 I was diagnosed with hyperinsulinemia. In the last month, I have had these wierd episodes. Not like a normal migraine. The left side of my body, usually starting with my arm, goes numb with a kind of burning feeling. My vision gets blurred and I feel light headed or dizzy. Sometimes my vision randomly gets blurred, without the headache. I'm walking, sitting or doing nothing and it comes out of nowhere. I just can't see. I'm 24 years old...too young for anything serious?? I don't want to go back to the doctor if it's just part of the headaches or the flu or something that isn't important. What should I do????
