Lymph nodes are glands all over the body which are usually small, bean like shape. Lymph nodes are fragments of the lymph structure, which conveys lymph fluid, waste substantial, and nutrients between the bloodstream and the body tissues. The lymph structure plays an important role in the immune system, and moreover help defense system against syndromes. When lymph fluids flow through lymph nodes, it is being filtered, trapping viruses, bacteria, and other foreign contaminations, which are next demolished by lymphocytes [special white blood cells].

Other conceivable but rare sources include certain prescriptions, for instance, Dilantin [anti-seizure medication phenytoin] and anticipatory prescriptions for malaria.
Complications or hitches
If swollen lymph nodes are caused by infection and are not been treated, these hitches may arise:
