[|Human|] A few days ago I found a small, hard lump behind my ear. It was painless unless I pressed on it. I guess it grew smaller, or deflated or something, because the bump isnt there anymore. However the spot where it was is numb. What is this?? When will I have feeling in that spot again?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have reactive lymph node enlargement due to some infection. So it increases in size at time of infection and gradually subside. If it recurs then you should take a course of antibiotics. If it does not respond to treatment then biopsy diagnosis is advisable. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health.
