A member asked:

Hi i have had a hard, pea sized lump behind my ear on the bone for about 15 years, it has never hurt me or increased in size... is it serious?

Dr. David Martin answered

Specializes in ENT - Head & Neck Surgery

Mastoid bump: I suspect that this is a reactive lymph node. It is small and not causing any issues. Nothing to do at this time.

Unlikely bad: Something that hasn't changed in 15 years is very unlikely something bad.... But anything on the skin can turn into something. I recommend you show it to your doctor next visit.
