So I've got an embarrassing situation. (Who doesn't in here?) I was diagnosed with UC five years ago, but a year later I was re-diagnosed with Crohns after requiring surgery on two fistulas in the perianal region. I'm on Humira and Lialda. A few days ago my tailbone started hurting. Today I noticed an acute pain, and it appears there is a fistula formed and infected in my butt crack, near the top at my tailbone. For years I have had this little dimple/hole at the very top of my butt crack that occasionally gets sore and bleeds. This fistula is below that little dimple two inches or so. My regular GI doc is on maternity leave until the end of the month. I have an appointment with her, but I am considering a trip to the ER. I'm experiencing nausea, tailbone area pain, and my existing setons are tender. Does anyone have experience with this?
