So I m a 20 year old female with no problems with my medical history. Tonight I noticed a lump right above my left temple, and I m super nervous about it. I rarely ever have any acne so I know this isn t the case. It s a little smaller than a dime, it doesn t hurt to touch it, and it seems to be moveable.. I can t really tell. Since I noticed it I ve began to have a headache and a pressure feeling behind my left eye, probably just from worrying, I guess. I didn t hit my head on anything, but it feels like a knot almost. I m scared its a tumor or something but it showed up so suddenly... what could it possibly be??
