You should definitely see a doctor. When I was in middle school, probably around 14 I suffered my first acute confusional migraine. This was due to over exertion and no food intake that day. The migraine put me in the hospital for two days. I don't remember anything that happened while I was in the hospital. Apparently I was in what doctors call an altered state (probably due to pain). I was combative, and it took four security guards at the hospital to subdue me and strap me to a gurney. This is all second hand knowledge considering I have no memory of this. My symptoms started with a blurring of my vision, inability to read, and progressed to a numbness up the right side of my body including my mouth, soon I had a splitting headache, after that I don't remember anything. I "woke up" (remember i was fully conscious I just don't remember anything) two days later with a catheter in, laying in a hospital bed, in the intensive care unit. Turns out I had this acute confusional migraine, the confusional part meaning i was wacked out of my head out don't remember anything. It's still a mystery as to what definitely triggers these for me but a sure fire way for me to have one is if i exercise heavily on no food. I've learned to deal with them and always always am properly nourished before I workout now. It's not only exercise that triggers these migraines, sometimes it can be during times of extreme stress, but the symptoms are the same. Loss of vision, right half of body numbness and splitting pain. I've never had one quite as intense as the first i.e. put me in an altered state and end up in the hospital but it does put me out of commission for a day or two. I usually have the misfortune of getting one of these migraines roughly every 18 months for some reason or another.
I guess this is a really long way of saying don't disregard your headaches! Your body is trying to tell you something and you should pay attention to it.
