A hair cyst, also known as a pilonidal cyst, is a small, fluid-filled sac that forms in the skin. It typically occurs at the base of the spine or in the area between the buttocks, where hair and sweat can accumulate and create an ideal environment for bacterial growth. Hair cysts can range in size from a small pimple to a large, painful lump.
The primary cause of hair cysts is ingrown hairs that get trapped in the skin. When hair follicles become blocked, bacteria can multiply, leading to an infection and the formation of a cyst. Other factors that can contribute to the development of hair cysts include a family history of the condition, hormonal changes, and trauma to the skin.
Hair cysts can cause a range of symptoms, including pain, tenderness, and redness in the affected area. In some cases, a hair cyst may become infected and lead to the development of an abscess, which can cause additional symptoms such as fever and drainage of pus from the cyst.
Treatment for hair cysts typically involves draining the fluid from the cyst and removing any hair or debris that may be trapped inside. This can be done in a doctor’s office using a local anesthetic to numb the area. In some cases, antibiotics may be prescribed to treat an infection associated with the cyst.
If hair cysts recur frequently or do not respond to treatment, surgical intervention may be necessary. This may involve removing the entire cyst, along with any surrounding tissue that may be infected or inflamed. In some cases, the surgical wound may need to be left open to heal from the inside out, which can take several weeks.
Preventing hair cysts involves practicing good hygiene and avoiding activities that can cause skin irritation or trauma, such as sitting for prolonged periods of time or wearing tight clothing. Maintaining a healthy weight and avoiding excessive sweating can also help prevent the formation of hair cysts.
