A hair cyst, also known as a pilonidal cyst, is a common condition that can occur in anyone with hair follicles. It is a sac-like structure that forms under the skin and is filled with fluid, hair, and debris. The cyst usually occurs in the area between the buttocks but can also appear on the scalp, face, and neck.
Symptoms of a hair cyst can vary from person to person, but common signs include:
Pain: The cyst can cause discomfort or pain, especially when sitting or lying down.
Swelling: The area around the cyst may become swollen, red, and tender to the touch.
Drainage: The cyst can release a foul-smelling discharge, which can be thick, yellow, or bloody.
Hair protrusion: If the cyst is on the scalp, hair may protrude from the center of the cyst.
Recurrence: Hair cysts tend to recur, so multiple cysts may develop over time.
In some cases, a hair cyst can become infected, leading to more severe symptoms. Signs of an infected hair cyst include:
Increased pain: The pain may become more severe, and the area around the cyst may feel hot.
Fever: The person may develop a fever or chills.
Abscess: The cyst can become an abscess, which is a pocket of pus under the skin.
Red streaks: Red streaks may appear on the skin, indicating that the infection is spreading.
If a hair cyst becomes infected, it is important to seek medical attention as soon as possible. Left untreated, an infected hair cyst can lead to serious complications, such as sepsis, which is a life-threatening condition.
In summary, a hair cyst can cause discomfort and pain, especially when sitting or lying down. The area around the cyst may become swollen, red, and tender to the touch, and the cyst can release a foul-smelling discharge. If the cyst becomes infected, the person may develop a fever or chills, and red streaks may appear on the skin. It is important to seek medical attention if an infection is suspected.
