Displacer

hey everyone,
I been meaning to ask people about this for a long time, but known if i've gone to the doc I would have to pay thousands for biopsies and such. For about 5 years now I have had two painless, pea size lumps on the left side of my neck just inside my hairline. they are right next to each other. Sometiems I think I feel the upper one pressing against the base of my skull but my dad thinks thats just because I'm aware of them. I don't think they're lymph nodes since they don't slip around and they havent gone down nor got bigger in that period of time. My folks think that it could have bee some kind of scar tissue from carrying a heavy school back for years - but I'm not exactly sure - does anyone have any idea what they are? if you need more information just post here and I'll reply.

Thanks in advance!
