Enlarged lymph node? i am a sixteen year old female. i've had something bulging from under my jaw for two weeks now. i've noticed it getting larger quickly, also becoming more and more painful. my friend said it might be a swollen lymph node. i've done so

Hello. : Hello. I can't diagnose your condition. However, a lymph node can become enlarged for more reasons that a sore throat or cough. An infection of a gum, a canker sore - these are just a couple of examples. Lymph nodes drain areas of inflammation or infection. I am glad that you will be seeing the doctor tommorrow, so that it can be properly assessed and diagnosed. Take care.

You : You absolutely should get this investigated. A physical examination, comprehensive medical history (and dental history) as well as blood tests might be necessary to diagnose. I would start with your physician and if the cause is unclear follow up with your dentist for an examination and necessary xrays.
