Lymph node: Probably nothing of concern. The differential diagnosis generally would be a reactive lymph node versus an epidermal inclusion cyst. This could be removed to be sure however with growth or changes. An Otolaryngologist would be able to determine this readily on physical exam.

Bone (Definition)

Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more

May be normal: The mastoid tip is a bony protuberance behind the ear. Some people suddenly notice it and think it's abnormal. Is it really a "new" bump? If so have evaluated by your md.

Mass: It doesn't matter what I think it might be based on the limited information you have provided, it needs to be seen by a doctor. I'm not sure why you have been watching it for "awhile" but now sought medical attention on line instead of in person but you already know you need medical evaluation. See your doctor.

Cyst: Most likely a benign (not cancer) cyst. Don't worry. To be sure, have a doctor see it. Primary care is fine. No hurry unless growing or painful. Hope this helps!

The bone behind my left ear is swollen and very painful like a burning sensation. Have a lump where ear meets jaw. Could this be a mastoid bone infect?

Unlikely: It is impossible to have a mastoid infection without a middle ear infection. The tendons of the large neck muscles attach on the mastoid bone and you could have either a tendonitis or myositis. The lump where the ear meets the jaw could be the parotid gland tail. See an ENT doctor for a specific diagnosis.

Rock hard, pea sized non tender non movable bump over mastoid bone behind left ear. Been there for 3 months does not change in size? Concern?

Follow: Likely a safe lymph node or if non mobile a small bone. It is tiny and non mobile and does not change. A US may be able to define it further but I'd doesn't sound bad. All the best.

Daughter just found bony bump behind ear. Hard smaller then a bb. Pcp says no lymph nodes thinks cartilage. Bone spur? No xrays done. I'm worried??

Not sure: Since it is smaller than a BB it is probably nothing to worry about. X rays are not likely to show much in this area. Just keep an eye on it and if it should start getting larger, then ask again for an evaluation. Meanwhile, ask her not to rub or mess with it (or you either!) Just check once a week or so.
