How do you tell if your lymph nodes are swollen? Are you not supposed to be able to feel them at all? So if you can feel them does that mean they are swollen? I swear I have always been able to feel my lymph nodes in the groin area? I can now anyway and since I am already concerned about some colin issues this has me really concerned. I also think I have always been able to feel my nodes in my neck. Please help me understand. I am so worried about cancer that I can't think straight.
