I have loads of them - on my foot, calf, near my kidneys on both sides (if someone pokes me in the sides, I'm liable to get punchy), above my arse, on my spine (annoying), on my arm. Runs in the family as both mum and sis have them. They are all quite small, so only even vaguely noticeable when my bodyfat is low, but easily felt.
GP said I can have as many as I like removed, but he advised against. I think that implies you can get them done without charge.
