I woke up , though I had a headache but top of scalp on left side is where the pain is. starts at night & get sharp pain, left ear starts hurting & get nausea. mornings left side nostril stuffed, tearing in left eye but pain still top of scalp. what is it? migraine, sinus headache or something worse? Can't see my doc. until next wk, she's on vacation. Any suggestions?
