So I'm 17, and a little over a week ago I started getting daily headaches. I was getting some acne on the back of my head that were hurting so I thought that this could be the cause, but since then it hasn't stopped. The headaches, generally, don't last that long and aren't that severe, but once in a whole, especially one night, it was very bad, with a lot of pain like around my eye (which has always been my most common headaches for as long as I can remember). Then a few days ago I happened to hit my head fairly hard and now in addition the top of my head hurts to the touch. Does anyone know what the cause of my headaches is? Note that they are NOT migraines, as I have had them in the past. Also, should I be concerned? Any help would be greatly appreciated. Thanks!!
