I have a lump under my jaw that is getting bigger.I have had it for about a year, it started out painless and wasnt really noticable unless I drank something cold but now it is very hard and tender and getting bigger and can be seen easily by others and is really bothering me. I have also had swollen lymph nodes on both sides of my neck and a lump over my collarbone that I have had for a couple of years it started out soft and painless but it seems a lttle bit more firm.I am also having some headaches and ear pain and night sweats on my neck and chest. I am supposed to see a neurologist in next month for my head and ear pain.I would like to know if my lumps could be a sign of something serious and any advice would be helpful...Thanks...psalms27
