Sorry if this sounds a bit gross, I'll try to be brief!
A few weeks ago I felt a small round raised area developing behind my right ear, about halfway between the hairline and the back of the ear, and almost halfway up from the bottom of the ear. Within a week or two it became textured like a scab, except that I can't pick it off like you could a scab. I suppose the circumference is about the size of a garden pea, although it's only raised by a couple of millimetres.
Soon after it came up I was at the GP for something else. He said there was nothing there, basically, and since it hadn't become the size and consistency it is now, I let him brush it off. But it has been there for weeks and doesn't seem to want to go away. It's not squeezable, doesn't seem to ooze anything, rarely itches, but feels rough under my fingertip. I don't have anyone close to look at it for me, and am a bit concerned that it might spread.
Probably nothing, but can anyone recognise what I'm describing?
