By "it's probably nothing", as bad as this is (because they're not explaining it to you) they're saying that it's nothing serious...i.e. it's not cancer, or something that can hurt you now or later on. They know that there's something under your skin (probably a lipoma, or fibroma), they realize that it's just an overgrowth of tissue, they realize that it might be a little uncomfortable, but from their point of view, there's really nothing they can do about it except for perhaps slice it out. You can ask if they can get them sliced out, but know that if the doctors aren't asking for further tests and biopsies, they're fairly content that it's nothing serious. I just wish they had said that to you more explicitly.
