How long have you had this swollen and painful lymph node?
Lymph nodes are small,bean-shaped glands that are located throughout the body. Their role in the lymph system is to carry lymph fluid, nutrients, and waste material between the body tissues and the bloodstream. The lymph system plays an important role in the immune system.
