Furunculosis and Carbunculosis


Furunculosis and carbunculosis

are skin infections that form lumps and pus, called furuncles and carbuncles. A furuncle (abscess) forms when a hair follicle and the skin surrounding it become infected. A carbuncle is made up of multiple furuncles, and goes much deeper into the skin. Furuncles and carbuncles are usually caused by bacteria.

Common symptoms include the following:

  • A furuncle usually starts as a small, firm, red lump under the skin. The lump usually appears in the neck, face, armpits, thighs, or buttocks. It may become painful, swollen, and full of pus.
  • A carbuncle usually occurs on the back of the neck or side of the thigh. It is a group of small, shallow abscesses that connect with each other under the skin. A carbuncle may easily open, drain pus, and form an ulcer on the skin. The skin then slowly heals and a deep scar may develop. You may also have other symptoms, such as fever, chills, fatigue, or pain.

Seek care immediately if:

  • You have a fast heartbeat or chest pains.
  • You have trouble breathing all of a sudden.
  • Your symptoms do not improve or are getting worse.
  • Your wound has pus coming out or has a foul smell.

Contact your healthcare provider if:

  • You have a fever.
  • You have chills or a cough, or feel weak and achy.
  • You have increased pain, redness, or swelling around the infected area.
  • You have questions or concerns about your condition or care.

Treatment for a furunculosis and carbunculosis

may include any of the following:

  • Medicines:
    • Antibiotics help treat a bacterial infection.
    • Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Acetaminophen can cause liver damage if not taken correctly.
    • NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
  • Incision and drainage is a procedure to drain the fluid or pus that has collected in the infected area.

Manage your symptoms:

  • Apply a moist, warm compress for 30 minutes, 3 or 4 times a day, or as directed. Warm compresses help decrease pain and swelling. They may also help drain pus and speed up healing.
  • Care for your wound as directed. You may need to apply bandages with medicine on them. You may need to wash the wound carefully with soap and water. Dry the area and put on new, clean bandages as directed. Change your bandages when they get wet or dirty.

Prevent the spread of furunculosis and carbunculosis:

  • Keep your skin clean. Wash your skin and hair every day. Wash your hands often. Use soap and water. Use germ-killing hand gel if soap and water are not available.
  • Apply lotion or moisturizing creams to your skin regularly. Stop using them if they sting or irritate your skin.
  • Avoid contact with other people's wounds. Keep any wounds clean and covered with clean, dry bandages until they heal. Place used bandages in a sealed plastic bag when you throw them away.
  • Do not share personal items. Use your own towel, soap, clothes, and other personal items.
  • Wash laundry correctly. Keep an infected person's laundry in a plastic bag until it is washed. Wash with detergent and hot water. Dry the items on the hot setting.

Follow up with your doctor as directed:
