[/INST] Hi, dear. I have gone through your question. I can understand your concern. You have ringing sensation in ear.  You also have some lymph node enlargement.  Furthermore, you may have some upper respiratory tract infection. Furthermore, you should take a course of antibiotics.  If lump doesn't respond to treatment then you should go for fine needle aspiration cytology of lump. It will give you exact diagnosis. Then you should 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. </s>
