Wait and watch for 2-3 days.

First of all, don't worry. A bump this small on the lower lip usually resolves on its own. Try pressing it, if it can be compressed, you dont need to worry at all as it is most likely a mucocele (saliva filled pimple of mucosa). It is always advisable to visit a clinic to get an incisional biopsy done. (They take a tiny part of the bump and then diagnose the exact problem under a microscope in a pathology lab). Rest assured, keep well hydrated. Load up on your multivitamins and do avoid sour foods. It's all okay. No need to worry.

Yes u can wait for 1-2 days.. still if it doesnot heal then get it removed as it's a mucocele. It may cause problem later on.

It should be removed and send for biopsy Mucocoel
