I have no idea where this pink bump came from and its not hitting my head with anything. more of a mole onlu tiny bit squishy.any what it is?

There are several potential causes for a pink bump on the head that is not caused by trauma. Here are a few possibilities:

- Sebaceous hyperplasia: Sebaceous hyperplasia occurs when the sebaceous glands in the skin become enlarged. These bumps are usually small, round, and yellow or flesh-colored. They are most common on the face, neck, and chest, but can also occur on the scalp.

- Keratosis pilaris: Keratosis pilaris is a common skin condition that causes small, rough bumps to form on the skin. These bumps are often red, pink, or white in color. They are most commonly found on the upper arms, thighs, and buttocks, but can also occur on the scalp.

- Molluscum contagiosum: Molluscum contagiosum is a viral infection that causes small, pearly bumps to form on the skin. These bumps are usually pink or flesh-colored, and they can be itchy or uncomfortable. Molluscum contagiosum is spread through direct contact with an infected person or animal.

- Dermatofibroma: A Dermatofibroma is a common, non-cancerous skin growth that typically appears as a small, firm, round, or oval bump on the skin. It can be pink, red, or brown in color, and it may be tender or itchy. Dermatofibromas are often found on the arms, legs, and trunk.

- Skin cancer: In rare cases, a pink bump on the head could be a sign of skin cancer. If you are concerned about a bump on your head, it is important to see a dermatologist for evaluation.

If you are not sure what is causing the pink bump on your head, it is important to see a doctor to get a diagnosis. The doctor will be able to determine the cause of the bump and recommend the best treatment options.
