<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a large lump in front of my right ear and my glands are swollen on my neck I believe they are my lymph nodes. The lymph nodes are sore in my neck and my jaw is a bit sore, but other than that I have no illness. Im not sure if I should see a doctor. I know they say that when your lymph nodes are swollen it is a sign of infection, but I have had no fever and no sickness. What could this be?  <response>: Hi, Welcome to Chat Doctor. The large lump in front of your ear could be due to parotid gland swelling, and with the presence of lymph nodes in the neck and a sore jaw, it is more likely to be a malignant growth of the parotid. I would strongly recommend that you show it to a surgeon for a clinical evaluation and get needle biopsy of the parotid and the lymph nodes to help reach a diagnosis. As further management will depend upon these evaluations. Hope I have been helpful.
