External hemorrhoids can be washed with warm water, but the temperature should not be too high, generally controlled below 40 degrees Celsius. Washing external hemorrhoids with warm water can promote local blood circulation and relieve the anal swelling caused by external hemorrhoids. At the same time, it can also remove secretions on the surface of the hemorrhoids, which helps to avoid inflammatory edema in external hemorrhoids. However, the water temperature must not be too high as it could scald the skin around the anus or cause dehydration of the perianal skin, leading to discomfort. Clinically, external hemorrhoids are mainly classified into four types: excess skin hemorrhoids, varicose vein hemorrhoids, thrombotic hemorrhoids, and inflammatory hemorrhoids. Depending on the type, the treatment methods differ. For inflammatory and thrombotic hemorrhoids, it is generally recommended to undergo early hemorrhoidectomy to prevent severe anal pain and serious impact on the patient's life.
