I have a lump on my throat directly under my right jaw in line with my ear lobe. no pain or marks but if i rub my throat i can feel it. what is this?

Cyst vs node: If this is a persistent problem, your physician can determine whether this is a branchial cleft cyst or an enlarged lymph node. If it is hard, gets fixed to the surrounding tissues, or continues to grow after 2 weeks, be sure to see your physician to rule out something serious but treatable, such as hodgkin's. Good luck.

Many possibilities: Everything from nothing to a benign growth in your saliva gland to lymph nodes. You need to see an ENT doctor for an evaluation.
