Mucocele on lip

So, I'm pretty sure I have Mucocele at specific sites in my mouth. They seem to recur every few months, but are pretty small before they rupture. Mine are filled with a blueish/purple fluid and do not bleed. These are, for the most part, a minor inconvenience.

Unfortunately, I have a similar blister that forms on my bottom lip where my upper and lower lips meet. Obviously, I need to see a doctor, but do any of you know if Mucocele occur on the lips? I have a bad habit of biting my lips. My lips also get dry and peal. I guess what I'm asking is if you have been told by your doctors if Mucocele do indeed occur on the lips?

Also, what specific kind of doctor would you recommend I see? I don't want to go running to my local physician yelling, "It's a mucocele! Google said so!"

Thanks much.
