Sorry about that Laura. I hope they can remove it and it'll stay gone for a long time. My MIL had cysts on her scalp and one on her face too. She had them removed but they gradually would start to come back.
DH has them on his scalp as well, but so far refuses to get them removed. (They'd have to shave the hair in that spot.)
His doctor told him years ago that they're harmless. It sure bothers
me sometimes when I'm cutting his hair though.

I guess he's lucky they aren't in a spot where they can get irritated easily.
