Hi. After months of reading this very helpful forum I have finally plucked up courage to write something. I had a perianal abscess back in Jan 2015, then fistula surgery which led to a high up sinus tract. Five further EUAs and 9 weeks of flagyl/metronidazole only made things worse. The sinus has since made its way towards the surface. My surgeon opened up the tract to create a fistula last week and now I have a seton. I expected drainage from the wound site but am continuing to get pus from the back passage as well. Anyone got experience of this? Is it normal? Will things settle down over time? And finally, is it okay to sit down, or try to? I'm terrified of making things still worse. Thank you!
