Problem...again!

About 2 months ago, I developed a mucocele on my bottom lip after biting it twice in one day...My dad and sister have both had them also. Well..I went to the ENT and had it removed...now three weeks later...the mucocele has "popped" back up again!...I do not know what to do anymore since I'm going on a 2 week vacation next week and surgery just irritates the area more....It has been very disappointing to have the mucocele come back after I just thought I was done. Should I try salt water rinse, listerine, primrose oil?...I just want it gone without another surgery.....
