I'm afraid you'll have to overcome your embarrassment and see a doctor about this. I can't imagine that these amount to anything significant. You say, "They are not noticeable but it is weird because they have been there for years." On the contrary--the fact that they've been there for years means they aren't wird, just part of you.
For your own good, check them out. There's nothing to be embarrassed about.
Take care.
