I have, what seems to be, a swollen lymph node on the side of my neck. I noticed it 5 months ago and didn t give it much attention, since at that time, I wasn t feeling so great. Recently, I ve had some stiffness in my neck, low grade fever on/off, and I have been tired more then normal. The bump hasn t gotten any larger or smaller. I know I need to go to the doctors but I was wondering what could cause this. I do have a bad tooth on that side of my mouth but it hasn t been painful at all. Any suggestions? ~Feda
