I have a cyst on my arm (about 1 inch in diameter). My doctor says that I can have it removed, but that it's not necessary and that it might shrink again on its own. It hurts occasionally, expecially if it's accidentally bumped. I'd rather avoid a surgery if I can, but I have had this for a few years and it doesn't seem to be going anywhere. Has anyone had a cyst where it eventually just went away?
