i noticed 3days ago that i have a lump on the center on my scalp/head.. it is very painful to the touch and also hurts when i move my hair or tie it back. when it's touched it feels like it sends the pain throughout my head, and i have been getting bad headaches too.. i am going to go to the emergency room tomorrow, but i would just like some advice as to what this may be! please help! -kayla.
