Fluid filled bubble on lower lip

[ajb212]

I occasionally get a little "bubble' on the inside of my lower lip.  It is clear and fluid filled.  I seem to get one when I am stressed or my immune system is low.  Only once I got 2 at a time.  They start out small and sometimes get a little bigger.  The bubble or cyst doesn't hurt- but it is bothersome and gets sore when I bite it or try to pop it.  It usually goes away in a day or two- it pops on its own usually, but sometimes it is so bothersome I try to pop it.  Then it leaves a small white bump that eventually goes away.  Eating salty foods seems to aggravate it.  I have done some research- Is it some rare kind of inner mouth herpes? I don't get any bumps on the outside of my mouth- I only get them on the inner lower lip.  Could it be oral warts from HPV?  How do I prevent them?  Can I treat them? Is it bad to pop one myself?  I have been getting them often the past few months since I have been under a lot of stress and not getting a lot of sleep.

I just started getting a single one of those simple cyst on my inner lip filled with clear fluid. I pop it and in three days a small one comes back, about 0.3-0.4 cm in greatest deminsion. What are these??? Causes, treatments?

Next time you get one, check in with a dentist, they can tell you what it is and type of treatment.  Most common are mucoceles, but it could be any number of other things.

Sounds like canker sores.  I got them only as a child.  My folks put Campho Phenique on them, but I think they just go away with time on their own, like a pimple.  They are hard, but they do look like a bubble.  Annoying.  Try googling canker sores and see what it says.
