I have pain directly behind my right ear and I think it may be swollen. It hurts when pressure is on it or if I turn my head side to side. My sinuses havent acted up yet this year and i am not sick right now. At first I thought I pulled a muscle in my neck, but then realized its not in my neck but behind my ear. I've had this pain for 2 days now. What could this be? Should I see a doctor or wait a couple more days to see if the pain goes away?
