Hi, I have what seems to be a swollen lymph node on the backside of my clavicle (almost in my trapesious) area. I ve had it for about a month. It s small, hard, doesn t seem to move, and is not painful. I seem to get swollen lymph nodes often when I ve had a cold/virus, etc. I ve had a nasty cold that lasted approximately 2 weeks that I am still not over. I ve also had a sore throat on and off and coughing up stuff. At what point should I get the lymph node checked out?
