Why is the bone behind your ear tender and sore?

The bone behind the ear is called the mastoid bone. It is part of the temporal bone, which also houses the inner ear and middle ear. The mastoid bone is located just below the ear and behind the temple.

There are a few reasons why the mastoid bone may become tender and sore. One reason is an infection of the mastoid air cells. These are small pockets of air located within the mastoid bone. When they become infected, it can cause pain, swelling, and tenderness in the mastoid bone.

Another possible cause of mastoid bone pain is a mastoid abscess. This is a collection of pus that forms in the mastoid bone. Mastoid abscesses can occur as a complication of a mastoid air cell infection or from other infections, such as meningitis.

Finally, mastoid bone pain can also be caused by trauma to the head. This can occur from a blow to the head, such as in a car accident or sports injury.

If you are experiencing tenderness and soreness in the bone behind your ear, it is important to see a doctor to determine the cause and receive treatment if necessary.
