For about a day now I have had little sharp pains on the right side of my head, they come and go and just last a few seconds. It's not on the scalp, just internal. Yesterday as I was driving it happened several times back to back to the point where I pulled into a parking lot until they passed. This is the first time I've had this kind of headache. I'm an otherwise healthy 31 year old female, and I very rarely get headaches at all.
I've also had a twitch in my left eye, which is also very unusual (if I get them they usually last an hour or so, this is the first time I've had one all day), the twitching started about the same time.
What could be causing this?
