The mastoid process is the bony bump behind the ears.
The bump on the forehead filled with blood is most likely a pimple.
First of all, who is it that 'believes' this lump on your forehead is 'calcified bone'? If it was you or other persons who don't have a medical license, see a doctor. If your doctor believes the lump to be calcified bone, ask your doctor what should be done to remove it.
The doctor will tell you when you go see him about it.
a horn, possibly a sign that you're the antichrist.
There are actually two terms that could answer this question depending on the size of the projection/bump. My answer would be "process", however, that is usally associated with large projection/bumps whereas "eminence" is a term associated with small projection/bump. As for ANY bony projection or bump, I do not believe there is umbrella-like term for it.
mastoiditis
They could be a lot of things from benign cysts to worrisome tumors of the bone. The best way to find out is to go see your doctor.
by getting a penny hold it on your bump then push it down and rub it in cycle
Bumps happen when you get hurt. The bump is just swelling.
I would call a doctor and see what s/he says.
Some told me dogs that have the boney bump at the back of the head is called an intelligence bump........is this correct and if so what exactly does that mean? I know what intelligence is........LOL! Are these dogs smarter than others? I just don't know.
