Bumps on the buttocks when you have a fire can be a sign of inflammatory external hemorrhoids. Inflammatory external hemorrhoids are congested and edematous resulting in severe pain around the anus, a foreign body proliferating at the anal opening, and possibly blood in the stool. In this case, the first thing to do is to clear the heat and lower the fire, and you can take oral Chinese medicines such as Niuhuang detoxification tablets or Sanhuang tablets for symptomatic treatment. After the oral medication, the stool will also become more fluent. After the stool, use warm water or potassium permanganate water to sit in the anus to improve the blood circulation around the anus, and the enlarged bumps can be reduced to some extent. At the same time, apply hemorrhoid cream at the anal opening, such as Anal Tai ointment or Ma Yinglong hemorrhoid cream, which has the function of clearing heat and detoxifying, reducing swelling and relieving pain. Through the above treatment program for about 3-5 days, the enlarged bumps at the anal opening can shrink a bit and the anal pain symptoms can be improved accordingly.
