I am a 20 year old male and I have a hard lump the size of a pea on my left jawline.  It does not hurt at all when i touch it and I can easily move it around.  I have had this lump for roughly a year and just want to make sure it is not cancer or anything bad.  The lump is roughly halfway between my ear and mouth and rests on the jawline.
Thanks for your query, I have gone through your query. The lump you are describing is nothing but an inflamed and enlarged lymph node secondary to any infection in the oral cavity. Nothing to be panic, consult an oral physician and get it evaluated. If there are any infection like tooth or gum infection, get it treated. Meanwhile you can take a course of antibiotics like amoxicillin and metronidazole(if you are not allergic)I hope my answer will help you, take care.
