<human>: I am 33years old and female. I have a lump behind my right ear that I discovered yesterday. It is flesh colored and feels hard and bony. It is the size of a dime right on my mastoid bone. I have not been feeling Ill. Am wondering if my glasses could be rubbing on the bone causing inflammation or if it is more serious.
<bot>: Hi! Welcome to Chat Doctor! Well, if I were your family physician for this complaint of a flesh colored and feels hard and bony lump behind the right ear, I would just think of some benign conditions and convince you not to worry at all! However, possibilities are : 1. Neurofibroma/dermatofibroma2. Enlarged lymph node due to chronic infection in the scalp, Dan Chat Doctor.  Benign osteomaOnly a microscopic examination and clinical assessment can confirm what is it therefore pleasing don't worry and see your doctor for relief or revert to us if necessary!wishing you good health!w
