I have a hard knot around my belly button with a soft bubble next to that. It is very sore to touch & is throbbing causing a lot of pain. I started Flagyl in the hopes it can clear up any infection that may be there. This is in the same area that I had a fistula from the pouch to the abdomen 6 years ago. I am seeing Dr. Remzi in 3 weeks for another fistula.....is there any danger of waiting to see him to deal with this or should I see someone right now? I don't want to run the risk of someone lancing it causing more problems but, I don't want this to explode either. I had that happen before! I just can't seem to catch a break! Any advice? Thanks!
