Hi Doctor want to ask about anal fissure I have had anal fissure surgery 25 days ago, and told doctors to soak in salt water for 15 minutes, now it is 25 days, but I felt a little blain in the anus , few doctors advised to soak the permanganas calicus, and i already soak with permanganas calicus for 5 days. if it is true that I do?, can I soak with liquid Dettol ?
