Hello Thank you for trusting HCM Dear patients with out symptoms may won t need surgery,just diet changes with life style modifications sufficient but symptomatic cases need surgery.surgery for fistula-in-ano should not be performed for definitive repair of the fistula in the setting of anorectal abscess (unless the fistula is superficial and the tract is obvious). In the acute phase, simple incision and drainage of the abscess are sufficient. Only 7-40% of patients will develop a fistula. Recurrent anal sepsis and fistula formation are twofold higher after an abscess in patients younger than 40 years and are almost threefold higher in nondiabetics. so take sitz bath ,take high fiber diet if symptoms not improved please consult your doctor he will examine and treat you accordingly. I think I answered to your question if you have more questions feel free to ask. take care
