I had radiation for cancer of the tongue and then last month had to have a neck dissection, removing lymph nodes and part of my tongue. The problem is now, a month after surgery, some very, very painful swelling is taking over my jaw and my life. Also, I have mucus thicker than "wallpaper paste" (as one lady said)and it stinks to high heaven. Should I be worried about an infection even though I don't have a fever?
