Lump on my labia

[anie]

I have a lump on my labia.  This is not the first time it has happened.  I started getting them 4 years ago after I had given birth to my first child.  It was lanced in emerg.  The next time was approximately a year later when they marsupialized it in surgery(It is not a bartholin's cyst).  Since then, the lump comes and goes in about 2 days.  Just recently, the lump came for 2 days before it burst and then the next day it reappeared for 2 more days before it burst again.  The occurences are mre frequent now.
It is very painful (like something sharp rubbing in there) which makes it hard to carry on basic activities like walking or sitting.  I have been told by my doctor that they are nothing and there is nothing that can be done to prevent it or burst them other that sitz bathing.
If there are any ideas, I would appreciate the input.
