I have a red patch on my hairline head it hurts when touch it. It is also kinda big. What it?

There are a few possible causes for a red, painful patch on your hairline. Some possibilities include:

* Ringworm: Ringworm is a fungal infection that can affect the skin, nails, and hair. It typically causes red, itchy, scaly patches on the skin that may be painful.

* Folliculitis: Folliculitis is an infection of the hair follicles. It can be caused by bacteria or fungi, and it typically causes red, swollen, and tender bumps on the skin.

* Sebaceous cyst: A sebaceous cyst is a noncancerous growth that develops from a blocked oil gland. It typically appears as a small, round, firm lump under the skin that may be painful.

* Skin cancer: Skin cancer can sometimes appear as a red, scaly patch on the skin that may be painful.

If you are experiencing a red, painful patch on your hairline, it is important to see a doctor for diagnosis and treatment. The doctor may perform a physical examination and may also order tests, such as a biopsy, to determine the cause of the problem. Treatment will depend on the underlying cause.
