What could a bump on your forehead be that is somewhat sore if you did not hit head anything and have no idea what it from?

A bump on the forehead that is somewhat sore and appears without any obvious cause could be a variety of things. Here are a few possibilities:

1. Cyst: A cyst is a sac filled with fluid or other material that can develop anywhere on the body, including the forehead. Cysts can be benign or cancerous, but most forehead cysts are benign. They are usually not painful, but can be sore or tender to the touch.

2. Lipoma: A lipoma is a benign fatty tumor that can also occur anywhere on the body, including the forehead. Lipomas are usually soft, movable, and painless, but can sometimes cause discomfort or pain if they grow large enough.

3. Hematoma: A hematoma is a collection of blood that forms outside of a blood vessel, often as a result of an injury or trauma. If you have recently experienced a head injury, even a minor one, it's possible that the bump could be a hematoma.

4. Abscess: An abscess is a localized infection that can form in any part of the body, including the forehead. Abscesses are usually painful and tender to the touch, and may also be accompanied by fever, chills, or drainage of pus.

5. Skin tag: A skin tag is a small, benign growth of skin that can occur anywhere on the body, including the forehead. Skin tags are usually not painful, but can sometimes be irritated by clothing or other objects.

6. Insect bite or sting: If you've been bitten or stung by an insect, the resulting bump could be located on the forehead. Insect bites and stings are usually painful or itchy, and may also be accompanied by swelling or redness.

7. Allergic reaction: An allergic reaction to a substance such as food, medication, or insect venom could cause a bump to develop on the forehead. Allergic reactions can also be accompanied by itching, hives, swelling, or difficulty breathing.

If you're concerned about a bump on your forehead, it's a good idea to see your doctor for evaluation. They can determine the exact cause of the bump and recommend the best treatment options.
