Lymph node worries or overreacting?

As a hypochondriac, I usually am afraid of having a serious illness. In my case, I worry about my lymph nodes so much that I compulsiely check them, because usually they will help out come time of infection. So after checking the main lymph node sites (armpit, neck, groin) everyday, I actually have yet to find something bad. I feel a lot of pain and discomfort in these areas and automatically ume there is a problem with my nodes, but they kinda feel normal. My question is could I be suffering from some other ailment like arthritis of some sort, or just overracting, as usual?
