About a month ago, I had to have an abscess treated between my rectum and my vaginal area, more on the buttock cheek. Antibiotics allowed it to drain well. A surgeon looked at it and recommended the antibiotic vs. surgery. I have had a fistula in the area for many years -but no major flare ups until now. I am 51 year old female. This weekend, it started burning and itching and becoming inflamed again. I finally looked at it with a mirror, which I hadn t done at all, and I was surprised to see a red inflamed butt cheek with a 2 inch elongated bruise with an open sore on 1 end. I took a hot bath and used Neosporin on it,and it has since drained (mainly thick blood). It feels better now and may be healing -but what the heck is this? Is this normal with fistula?
