I have a very painful lump on the (left of center) top of my head (which, after looking at several sites, I'm not sure, now, is it my head, scalp, etc....it's on the top of my head/scalp?? I don't know how, don't remember hitting it, however, it is VERY Painful to touch it or around it, brush my hair....in fact, it hurts constantly! It looks white on top the area, yet, surrounded by redness. I've had it for a few days, but it keeps getting larger and more painful, everyday. Today, I also noticed a knot in front of my left ear and a swelling on the left side of my forehead. My forehead is not sore, however, the knot in front of my ear, is. I can't find any answers to the related inquires I've googled?? Can you please answer at your earliest convenience? Thank you, so much!
