Hi
Welcome to the MedHelp forum!
Painless lump behind the ear could be Lump behind the ear could be folliculitis (hair follicle infection), lipoma (localized collection of fat), a cyst, an inflamed lymph node or a neurofibroma (localized harmless swelling in of nerve and connective tissue). Watch the lump. Do not touch everyday but once in 10-15 days. If the lump increases in size, becomes painful, changes color, bleeds, changes shape or consistency or more similar lumps appear then consult a doctor.
Hope this helps. Take care!
Just to add, its on the back of my ear. where the bone is, between my scalp line and ear
