Anal fissures usually take more than 10 days to heal using medication. However, the healing time will be different for each person because the depth of the fissure is different and the treatment method used is different. If the tear just occurred and the wound is not too deep, promptly use potassium permanganate dilution after sitz bath, and then with the use of Ma Yinglong hemorrhoid cream to apply the affected area. You may see significant improvement in about 5 days, and it may heal in about 10 days. However, if the fissure is deep, or if repeated attacks have formed old anal fissures, it is more difficult to cure. In this case, conservative treatment is basically useless and requires direct surgical treatment. After the treatment is properly maintained, you can generally recover in about half a month. So once the anal fissure occurs, it should be promptly treated with medication or surgery.
