Purplish red bumps in the anus are considered to be thrombosed external hemorrhoids. For example, drinking a lot of alcohol, eating spicy and irritating food, and over-exerting oneself during defecation may lead to the rupture of blood vessels in the perianal subcutaneous area, resulting in the formation of subcutaneous bruises. When the blood accumulates to a certain amount, it can lead to the formation of blood clots, resulting in the appearance of purplish-red bumps under the skin of the anus. At the same time, it can be accompanied by inflammation, pain and other symptoms. At this time, it is recommended to go to the hospital for examination and treatment. Under the doctor’s guidance, the thrombus can be relieved by taking local sitz baths with traditional Chinese medicine, applying hemorrhoidal ointment externally, and taking vasodilating drugs orally. If the symptoms are serious, the thrombus can be surgically stripped off, specifically follow the doctor’s instructions to actively cooperate with the treatment to avoid aggravation of the condition.
