Why do I have a pea-sized lump under the skin of my perineum?

A pea-sized lump under the skin of your perineum could be caused by a number of factors. Some possible causes include:

* Skin tags: Skin tags are small, benign growths of skin that can occur anywhere on the body, including the perineum. They are typically harmless and do not require treatment.

* Cysts: Cysts are sacs filled with fluid or other material that can develop in various parts of the body, including the perineum. They are usually benign and do not require treatment unless they become infected or painful.

* Hemorrhoids: Hemorrhoids are swollen veins in the anus and rectum that can sometimes extend into the perineum. They can cause pain, itching, and bleeding.

* Abscesses: Abscesses are collections of pus that can form under the skin due to infection. They are typically red, swollen, and painful.

* Lipomas: Lipomas are benign tumors made of fat cells that can occur anywhere in the body, including the perineum. They are usually soft, movable, and painless.

* Pilonidal cysts: Pilonidal cysts are a type of cyst that occurs at the top of the cleft between the buttocks. They are caused by ingrown hairs and can become infected or painful.

If you are concerned about a pea-sized lump under the skin of your perineum, it is important to see a doctor for evaluation. The doctor can determine the cause of the lump and recommend appropriate treatment.
