How to treat a slightly sore or irritated buttocks
Generally, mild breakdown or erosion of the buttocks may be caused by local moisture and friction, improper cleaning, perianal eczema, diaper dermatitis, or rupture of a perianal abscess. Depending on the specific situation, patients can improve the condition through general care, medication, or surgical treatment. Detailed analysis is as follows:

1. Local Moisture and Friction
Prolonged sitting or excessive sweating can cause dampness in the buttocks area, and clothing friction may damage the skin, leading to erosion. Avoid prolonged sitting immediately—stand up and move every hour. Wear loose, breathable cotton clothing, and gently pat the buttocks dry with a soft towel to keep the area dry.
2. Improper Cleaning
Vigorous wiping with rough toilet paper after bowel movements or frequent use of irritating cleansers can damage the perianal skin and lead to erosion. Switch to gentle wet wipes for cleaning, rinse gently with warm water, then allow the area to air dry naturally. Avoid using irritants such as soap.
3. Perianal Eczema
Moisture, allergies, or other factors may trigger perianal eczema; when the rash breaks open, erosion occurs, often accompanied by severe itching. Under medical guidance, topical treatments such as tacrolimus ointment or calamine lotion may be used, along with oral antihistamines like cetirizine hydrochloride tablets. Avoid scratching the affected area.
4. Diaper Dermatitis
In infants and young children, prolonged use of wet diapers exposes the skin to urine and feces, causing redness and erosion of the buttocks. Change to breathable diapers promptly. After each change, apply zinc oxide ointment and clean the buttocks with warm water. Avoid using talcum powder.
5. Ruptured Perianal Abscess
If a perianal abscess is left untreated, it may spontaneously rupture, forming an eroded wound with pus discharge. Immediate medical attention is required, typically involving incision and drainage surgery. Postoperatively, follow medical advice to apply mupirocin ointment topically and take cefuroxime axetil tablets orally. Keep the wound clean.
Daily care of the buttocks is essential—maintain dryness and cleanliness, wear properly fitting clothing to minimize friction, follow a light diet avoiding spicy foods, and ensure smooth bowel movements. If the eroded area fails to heal over time or is accompanied by fever or pain, seek prompt medical evaluation and treatment.
