Hello, my 31 year old husband has a hard lump on the front right side of his chin, along the jaw bone. It s not under the chin. It has developed in the last few hours and it s dime sized. He s had the flu (a bit of nausea, loss of appetite, headache, tiredness) for a few days. I m just wondering because I looked at a map of lymph nodes in the face and I didn t see that any are in the area where the lump is.
