I seem to have a swollen lymph node(s) in my neck. if i turn my head it aches. if i swallow it hurts a little. should i see my doctor?

Wait three weeks: This is probably a benign swollen lymph node from an infection perhaps a virus or skin infection it is less likely to be lymphoma or tumor. However if it persists for more than three weeks you should see your doctor.

Monitoring Centers: Lymphatic system absorbs/carries things too big to go into the arteries/veins like bacteria eaten by white cells and digested food. Lymph nodes "taste" the lymph for anything bad like bacteria, viruses, cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well.
