A boil-like bump near the anus might be an abscess or an infected follicle. If it becomes more painful, larger, or is accompanied by fever or redness, it should be seen by a healthcare professional.
A small bump that looks like a boil near the anus can be a sign of a bacterial infection. This can happen when a hair follicle or small pore gets infected, creating a painful, red, and swollen area. Sometimes, this type of bump is part of what’s known as a perianal abscess or bacterial folliculitis. In these situations, the bump might fill with pus, making it look like a boil. For treatment at home, you can start by gently cleaning the area with warm water and mild soap. Applying a warm compress or soak can help by reducing pain and swelling while encouraging the bump to drain naturally. Over-the-counter pain relievers can help manage discomfort. However, if the bump grows larger, becomes increasingly painful, with surrounding redness, or if you develop a fever, it is important to consult a healthcare provider. They may need to drain the bump or prescribe stronger antibiotics to treat the infection properly and prevent complications.
