Back of neck/beginning of skull tingling?

And also at the back of the throat, kind of. I've also felt dizzy, unbalanced, nauseated, and anxious throughout the day. It might have to do with the fact that I was reading last night, my neck felt awkward in every position I put it in. Also, my forehead and toes have been feeling weird. Should I see a doctor? Does anyone know what's wrong with me? I'm 13, if that helps.
