The anus is the lowest part of the digestive tract, the opening from which stool is passed out of the body. Anal discomfort includes pain, itching, or burning.
Discomfort in the anal area can take many forms, including pain, itching, or burning. It is rarely life threatening, but it can be quite annoying. There are several possible causes.
Causes of anal discomfort include:
Other causes are also possible. Sometimes, no cause can be found.
When a person has anal discomfort, the healthcare provider will need more information. These questions may be asked of the person.
Other questions may be asked as well.
Diagnosis begins with a medical history and physical exam. This may be all that is needed to figure out the cause of the discomfort. In other cases, further tests will be needed.
If an STD is suspected, a culture may be done to determine the exact cause of an infection. A culture is a test in which bacteria or other organisms are grown in the lab from a sample of tissue. Tissue is collected by using special cotton swabs to wipe the area around and inside the anus.
If inflammatory bowel disease is suspected, anoscopy or sigmoidoscopy may be advised. These are special procedures that allow a doctor to view the inside of the intestine. They both involve putting a small instrument into the anus that contains a light and a camera.
Prevention is related to the cause. For example, safer sex practices can help avoid cases from STDs. Avoiding anal sex can prevent cases from trauma due to this cause. Many cases cannot be prevented.
Most long-term effects are related to the cause. Anal discomfort from diarrhea usually goes away without treatment and has no long-term effects. Inflammatory bowel disease can cause serious problems throughout the body. These may include damage to the intestines, joint pain, and visual impairments. Anal cancer can sometimes cause death.
Anal discomfort is not contagious. However, if an infection is the cause, the infection might be contagious.
Treatment is directed at the cause. Excessive washing of the anus with soap is discouraged and often makes the pain worse. Most STDs can be treated with antibiotics. Inflammatory bowel disease is often treated with medicines such as prednisone to reduce inflammation. Medicine or hemorrhoid surgery may be used for hemorrhoids. People with anal cancer may need surgery, chemotherapy, or radiation therapy.
Side effects depend on the treatments. For example, antibiotics and sulfasalazine may cause allergic reactions or stomach upset. Surgery can cause bleeding, infection, or allergic reactions to anesthesia.
Outcomes after treatment are related to the cause. A person with diarrhea from an infection often feels better once the infection clears up. A person with inflammatory bowel disease often has repeated flare-ups of the disease. A person with anal cancer may die if treatment fails.
Any new or worsening symptoms should be reported to the healthcare provider.
