Hi
Welcome to the MedHelp forum!
It is difficult to comment without examination. 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). You may not have been sick but local infections like dandruff or a dermatitis too can cause a lymph node to swell.
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.
Alternatively you could consult a doctor and get a CT scan of the lump. Since you face bruises and blows, this could be a hematoma.
Please let me know if there is any thing else and do keep me posted. Hope this helps. Take care!
