Folliculitis is the inflammation of hair follicles due to an infection, injury, or irritation. Boils are pus-filled lesions that are painful and usually firm. Carbuncles are clusters of boils.
Folliculitis is the inflammation of hair follicles due to an infection, injury, or irritation. It is characterized by tender, swollen areas that form around hair follicles, often on the neck, breasts, buttocks, and face. Boils (also referred to as furuncles) are pus-filled lesions that are painful and usually firm. Boils occur when infection around the hair follicles spreads deeper, and are usually located in the waist area, groin, buttocks, and under the arm. Carbuncles are clusters of boils that are usually found on the back of the neck or thigh. Staphylococcus aureus is the most common bacteria to cause these infections.
The following are the most common symptoms of folliculitis, boils, and carbuncles. However, each person may experience symptoms differently.
Symptoms for folliculitis may include:
Pus in the hair follicle
Irritated and red follicles
Symptoms for boils may include:
Pus in the center of the boil
Whitish, bloody discharge from the boil
Symptoms for carbuncles (clusters of boils) may include:
Pus in the center of the boils
Whitish, bloody discharge from the boils
Tenderness and pain at the site
The symptoms of folliculitis, boils, and carbuncles may resemble other skin conditions. Always consult your doctor for a diagnosis.
Diagnosis of folliculitis, boils, and carbuncles are made by your doctor after a thorough medical history and physical examination. After examining the lesions, your doctor may culture the wounds (take a sample of the drainage of the wound, allow it to grow in the laboratory, and identify specific bacteria) to help verify the diagnosis and to help in selecting the best treatment.
Specific treatment for folliculitis, boils, and carbuncles will be determined by your doctor based on:
Your age, overall health, and medical history
Extent of the condition
Your tolerance for specific medications, procedures, or therapies
Expectations for the course of the condition
Your opinion or preference
Treatment may include:
Topical antibiotics (for folliculitis)
For carbuncles and boils, a warm compress may be used to help promote drainage of the lesion
Surgical incision (making an opening in the skin overlying the infection) and drainage of the pus
Oral or intravenous (IV) antibiotics (to treat the infection)
Cultures may be obtained to identify the bacteria causing the infection
Keeping the skin clean helps to prevent these conditions from occurring and is essential for healing. Scrub your hands with soap and warm water for at least 20 to 30 seconds after touching a boil and do not re-use or share washcloths or towels. Change the dressings often and place the dressings in a bag that can be tightly closed and thrown out.
