What Causes A Hard Lump On The Mastoid Bone?

I have found a lump behind left ear on mastoid bone, not the soft tissue directly behind ear. It is hard Like bone and immovable size of a quarter. Painful to touch and without touch. I have experienced headaches and some neck pain on left side. No ear pain. General fatigue. No sore throats or current infections to my knowledge. The tenderness and immobility as well as size is concerning. I have no insurance. It is not getting better.noticed about 3 days ago. It has gotten larger. Pleae help.

welcome to Health care magic.
1.It seems like a bony lesion - osteoid osteoma (immobile, no soreness, hard, no pain - suggest a bony lesion)
2.Atleast get an appointment with your GP and let the doctor examine the lesion.
3.If you are my patient, after examination i would have send you for a CT head for better evaluation, even HRCT temporal bone for better bony, and ear anatomy.
4.As it need to evaluate, weather there is any extension in the brain.
5.Initiall get an appointment. - good luck
Hope it helps you. Wish you a good health.
