Hello I Have a question about a small lump about the size of a lady bug in the back of my head. I wasn't born with this and don't know where is has come from. I remember discovering it about 8 or 9 years ago. When I push on it it moves a bit side to side, the lump is under the skin, if I toush it too much it starts to hurt and then I get a head ache. I thought a tumor maybe? But still I have no answers... If anyone knows anything please let me know
