Ummm, what could this be???

[~me~]

From what you are describing I have the exact same thing. Mine is actually on my bikini line. I have it looked at. They said it was a cebacious (sp?) cyst. I used to get them on my neck, I had the ones on my neck removed and will probably have this one removed at some stage as well. It's just that it is not in a convenient spot to do that without planning ahead Lol! A couple of times it flared up into a boil after having bikini waxing....ouch!
Definitely get GP to look at though, just to make sure.

Sounds like a fat deposit (fatty tumour) to me. Completely harmless. But best go to the GP and make sure
