I just got this bump on the back of my head 2days ago.
I was angry at the tyme I got it. I thought I was bitten
by a spider or a silver fish(a thousand legger is what we
call it),but there was no sign of any bite mark.I shaved
around the bump to see if there was any discoloration...there wasn't. It almost feels fluid filled at some spots and harder in others. It is about an inch in diameter. When I turn
my head to the right,I can feel tension...Im gonna go to
see a doctor
