[|Human|] I am a 25y/o female and i have a knot/lump on the back of my neck below my hairline. I have had it for a few days now, it came out of nowhere. The size is smaller than a pea and sometimes I feel a slight burning sensation coming from it. What could it be?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You mostly have posterior cervical lymph node enlargement. ITIS due to some infection in head and neck area.  You should complete a course of antibiotics. If it doesn't respond to treatment then biopsy diagnosis is advisable. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
