For anal redness and swelling, you can apply erythromycin eye ointment, which can be used as a local anti-inflammatory and pain-relieving agent. If it is caused by perianal eczema skin disease, you can apply flumethasone ointment. You should pay attention to the local hygiene and apply salt water baths every day to prevent infection, especially after defecation. Don’t eat spicy and stimulating food, because it will lead to local venous dilation and accelerate blood circulation, which is not conducive to the healing of the wound. In addition, in the case of diseases such as perianal abscesses, the simple application of ointment is not a complete treatment and requires timely surgery, incision and drainage, and detailed exploration of the internal opening and incision if necessary. The change of medication after surgery is also very critical because perianal abscesses, if not treated promptly and effectively, can lead to the formation of anal fistulas, intermittent changes of medication on the wound surface to promote healing, prevent the formation of scar tissue, and regular review.
