had from october

i had a mucocele from october to now jan whent to dentist he said leave it alone for now i had lanced it several times clear liquid came out and it went down it did breake open on its own after about three months now it is a small bump on the inside of my lip but seems to be very slowly geting better. the dentist said he has also had one and it would take some time to go away but if not to have a oral sergon look at it i have been a lip biter my whole life when i am thinking but have been chewing gum to help stop the biting thank you so much for this sight i was in a real panic when it first happened now several of my friends are no longer biting there lips
