Does cyst causes lump ?
Patient: I have a sebaceous cyst on the back of my head. Around the same time I noticed a small knot like lump on the side of my neck about 2-3 inches under my left ear. It is painful. Do you think that the lump is from the cyst? Or does it need to be checked for cancer? Doctor: Thank you for query.The lump behind the ear may be due to lymphnode enlargement due to infection in the scalp or ears.It may be any infection.So you may need oral antibiotics and examination for looking the site of infection so please consult doctor.
