Last January I had a tender swollen lymph node by right collar bone. Had lots of tests, blood work, mammogram, thyroid checked and everything came back negative. It went away in about 5 weeks. Now my glands under my neck by my jaw (same ones that swell when you have a sore throat) are swollen and tender. My doctor gave me antibiotics but still there. Not sure what I should do? What can this be? Why has my glands swollen twice in less than a year? I m a teacher and strain my voice. By lunch time my gland area feels like something is ripped.
