Sometimes i get mucocele bubbles on my lower lip, especially after i use the chapstick brand lip balm. what should i do about the bubble? pop it?

Lip bubbles: Although the mucocele bubbles will usually resolve on their own, popping them should not be harmful as long as you watch for signs of infection: redness, swelling, pain, pus. If these occur after using that particular lip balm, i'd consider using a different brand/formulation.

Mucocele: Is a rupture salivary gland that swells up.. Usually on the lower lip. Try salt water (1 tablespoon of salt in a cup). Most of them resolve by themsel. If not, see an oral surgeon so they can remove them.
