[|Human|] 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.
