I am 61 years old male and suffering from ano-rectal fistula for past 7 yrs. This disease had been diagnosed by my surgeon. The hole near perianal area closes for a month and gradually swells to a pea size and opens. Bleeding occurs and I do dressing with antiseptic solution for 3 days and the hole closes. There was no pain / problem for one month and then abscess develops, opens and bleeding takes place. This is recurring process. There was no problem till last 3 months, now the closing of hole is not taking place since I have type 2 diabetes (fasting blood sugar 123 mg per dl) and taking metformin 500 mg 1 bid. I want cure thru medicines (non surgical methods) and afraid of surgical intervention. Pl suggest pills, drops and other guidelines for getting rid of the ailment of anal fistula.
