Hello Painless lump behind left ear may be due to many reasons like infection/inflammation in scalp, ear,neck etc. It is generally a benign finding and underlying cause should be treated. Your son need proper clinical examination and ultrasound of lump can be done.FNAC of lymph nodes can also be done to assess exact nature of enlarged lymph nodes. Treatment depend upon findings.
