An abscess and a fistula are two medical conditions that can affect the skin and other organs. Both can cause pain, itching, and swelling, but they are very different conditions that require different treatments.
Abscess
An abscess is a collection of pus that forms in the skin or in other body tissues. It is usually caused by an infection, such as a bacterial infection. The area around an abscess is often red, swollen, and tender to the touch. It may be filled with a cloudy fluid, and it may be painful when pressed.
Fistula
A fistula is an abnormal connection between two body parts, such as between an organ and the skin, or between two organs. It is usually caused by an infection or an injury. A fistula may be filled with pus, but it is not usually as painful as an abscess. It may also cause itching and discharge.
Difference between an Abscess and a Fistula
The main difference between an abscess and a fistula is the type of fluid that is present. An abscess is filled with pus, while a fistula may contain a variety of fluids, including blood, mucus, and pus. An abscess is usually more painful than a fistula, and it is usually localized to one area. A fistula, on the other hand, may spread to other parts of the body and may cause more systemic symptoms, such as fever and chills.
