i have the same painless hard lump at the center of my forehead for 3 years now. it is not getting any bigger so i did not seek any medical help.
A hard painless subcutaneous bump that moves on a finger could be a callus. It is important to seek medical attention as soon as possible.
Large hard bump[assuming it bony hard] on the forehead, which you have had for years and painless must be a benign tumour arising from the frontal bone. But if it is suddenly getting larger and "looking weird" there IS A POSSIBILITY that it has undergone malignant transformation - simply means it might have changed into a cancerous one; usually it associated with pain. Consult a doctor as soon as possible. They will take a biopsy to determine the tumor's nature. Even if its malignant, there are highly effective treatments available. So waste no time.
...many things
Go to the doctor. Right now. You have a concussion. (How hard did you hit the door? Man!)
it could be swolen lymp nodes or just were you may have hit your head on something

I smacked him in the head hard.
If your child hit their head that hard, you should take them to the doctor right away.
If you've got a small hard lump on your forehead about being kicked, not only is it normal, it will likely go away.
Nothings wrong as long as they aren't massive. It's the shape of your skull!
