Hello Thanks for writing to us. Sometimes the Moisture from sweat or diarrhea may cause itching. If the anal skin stays wet, the skin begins to break down which in turn cause itching and pricking sensation. However Infections such as pinworms, yeast, and genital warts can also cause itching. In some cases the burning is due to the food. Try to see what are you eating in your diet. If you are having too much spicy food then stop taking it now. It can be the cause of burning. Avoid fried, spicy and precooked meals. Drink a plenty of water. Try to follow the undermentioned instructions. Initial treatment of simple itching is directed toward relieving the burning and soreness. It is important to clean and dry the anus thoroughly and avoid leaving soap in the anal area. Cleaning efforts should include gentle showering without direct rubbing or irritation of the skin with either the washcloth or towel. After bowel movements, use moist pads such as baby wipes, flushable moist wipes, and flushable anal cleansing wipes for cleaning the anus instead of toilet paper. If there is constant moisture present in the anus or stool incontinence, it may be necessary to clean the anus with moist pads between bowel movements. I hope i have solved your query. Still feel like asking anything then feel free to write me back. Thanks Dr. Tripat Mehta
