I had a pimple on my scalp which I get every couple of months but this time it's grown to the size of a gumball and throbs all day , but I can't touch it without pain like it hurts to lay on it ,brush my hair, or even put my hair up it hurts, I've been putting Neosborne on it and washing it with Peroxide for 4 days now and the swelling hasn't gone down it's been about a week since it's been here on my scalp I tried popping it and some puss came out and but the bump is still there and is hard to the touch and when I popped it I felt some pressure release
