Eye twitching and sharp pain on a single spot on the right side of my head. What!

I'm 16 years old and I've been experiencing a very sharp pain on a 2 inch spot on the right side of my head. The pain is really sharp, but usually lasts no more than 10 minutes. I feel it almost everyday, and sometimes about 1 hour before the pain starts I feel nausea and dizziness. I've been experiencing this pain for about 3- 5 months (I don't really remember when it started), but about 1 month ago I started experiencing constant eye twitching on my right eye. It doesn't hurt, but it is very annoying and it irritates my eye. My right hand and right side of my mouth twich sometimes, but it is really rare. But the eye twitching is constant. What could it be? My parents don't think its anything serious, so I don't want to bother them to take me to the doctor. Does anyone have any idea of whats going on?

Btw, I've never suffered any head trauma, I don't consider myself to be in severe stress (mild stress, but not severe), and I don't have any family history of neurological problems.
