perianal

Your anus is the opening at the end of your large intestine. It is where stool (poop) leaves your body.

Problems with the anus are common. They include:

• Hemorrhoids
• Abscesses
• Fissures, small cracks or tears in the lining of your anus
• Anorectal fistula, an abnormal tunnel from your anus or rectum to the skin surface
• Anal itching (pruritus ani)
• Cancer

Your symptoms will depend on which disorder you have. But some of the more common symptoms may include:

• Bleeding
• Discharge
• Itching
• Pain
• Swelling

To make a diagnosis, your health care provider will ask about your symptoms and medical history. Depending upon your symptoms, your provider may:

• Check the skin around your anus for anything that looks abnormal.
• Perform a digital rectal exam (DRE). For this exam, your provider inserts a lubricated, gloved finger into the lower part of your rectum to feel for lumps or anything unusual.
• Order tests, such as an anoscopy.

You may be embarrassed to talk about your anal troubles. But it's important to let your provider know about your symptoms, especially if you have pain or bleeding. The more details you can give about your problem, the better your provider can help you.

Treatments vary, depending on the condition you have.

Cellulitis is an infection of the skin and deep underlying tissues. Group A strep (streptococcal) bacteria are the most common cause. The bacteria enter your body when you get an injury such as a bruise, burn, surgical cut, or wound.

Symptoms include:

• Fever and chills
• Swollen glands or lymph nodes
• A rash with painful, red, tender skin. The skin may blister and scab over.

Your health care provider may take a sample or culture from your skin or do a blood test to identify the bacteria causing infection. Treatment is with antibiotics. They may be oral in mild cases, or intravenous (by IV) for more severe cases.

Strep is short for Streptococcus, a type of bacteria. There are several types. Two of them cause most of the strep infections in people: group A and group B.

Group A strep causes:

• Strep throat - a sore, red throat. Your tonsils may be swollen and have white spots on them.
• Scarlet fever - an illness that follows strep throat. It causes a red rash on the body.
• Impetigo - a skin infection
• Toxic shock syndrome
• Cellulitis and necrotizing fasciitis (flesh-eating disease)

Group B strep can cause blood infections, pneumonia and meningitis in newborns. A screening test during pregnancy can tell if you have it. If you do, intravenous (IV) antibiotics during labor can save your baby's life. Adults can also get group B strep infections, especially if they are 65 or older or already have health problems. Strep B can cause urinary tract infections, blood infections, skin infections and pneumonia in adults.

Antibiotics are used to treat strep infections.
