For the last two weeks I have been experiencing a dull ache pain on the left side of my head; behind my ear, around my temple maybe and it moves towards my eye. It's not like a normal headaches, I have migraines so it's different from those. If I press firmly it goes away otherwise it comes and goes every ten or twenty minutes. I've noticed that if i'm quite active they don't hurt as bad but when i'm still or if i move rather quickly, it's there. I'm worried. What could this be and should I see a doctor?
