Six months post chemo, radiation, and brachytherapy. A lymph node on the opposite side of my neck became swollen and tender. My ENT put me on an antibiotic and after two days, the node seemed to reduce and the soreness subsided. Third day (today) my jaw is very sore and it hurts when I open my mouth...I know...don't open your mouth!! Anyway,now I'm not so sure we are looking at an infection. Anyone experience a similar problem? I see my ENT again on Tuesday. In the meantime, I'll just hope things improve....
