my right ear hurts, has a buzzing noise, the right side of my face is a little bit swollen, not noticeable, my submandibular right lymph node seems to be enlarged and painful from time to time, especially when I wake up and move my head and sometimes when I eat. I was diagnosed with common cold (viral) and Eustachian tube dysfunction. I am on antibiotics, 3000mg per day. I have no longer pain in my ear, but the buzzing noise. I was taking also decongestants. My question is why the node is enlarged and will it go away?
