I had fissure surgery recently, and my doctor recommended using potassium permanganate in warm water for 20 minutes. After a few days, I went back to work, and when I walked, the skin around my anus started burning badly. This has been happening repeatedly. What should I do to prevent this? Please help.
After fissure surgery, to alleviate the burning sensation, apply a topical analgesic cream or ointment, take regular sitz baths with potassium permanganate as directed, and consider using a donut-shaped cushion to reduce pressure while sitting,
