help help help possible fistula again

Okay i have had fistula's pop open 3 times.  But unfortunetly, i have never seen what it looked like before it popped open.  I have a seton in right now, but with pain in my rectum for a while, i have been looking down there with a mirror upside down to see if i can see anything.  I just looked and i can see right next to my butt hole, there is a tract looking, bulge thing sticking out.  When i touch it, it feels itchy, and a little pain.  I don't want to freak out but i'm afraid this might be another fistula about to pop open. It's on the opposite side of my butt from the open fistula i have now.  Does anyone know what it looks like before it forms?  And if it is another one should i go to er or just sit around and wait for it to burst,  please help  =[

prednisone, cipro, prevaid, pentasa and some pain meds.  It's funny about the bath thing cuz last night i took a hot bath and it was after that, that i noticed it.  Now this morning the bulging tract looks like it's gone down, i mean you can still see it but it isn't pronounced as much.  Does taking the bath help it to pop open?   And i deceided to last night too that i wouldn't go to the er cuz there is prob. nothing they can do anyways, and when it opens I should feel better so i will just wait it out. 

I was worried I might be getting one... Mine bump is itchy ... it seems to be growing some too.. Doesn't hurt too much but is sore. I am worried now Karen
