Why do i get a headache on the right side of my head? i'm a 17 year old girl and they mostly happen in school

Possible Migraine: Unilateral headache with pounding is frequently Migraine. Read about this, see if it fits. Primary care doctors are very familiar with this and can be a big help. Stress, poor sleep menstruation and vision problems can all trigger Migraine (among others). Neurologists can also have a role if the headaches don't stop. Get an evaluation and I hope the headaches go away forever.
