Lymphatic Pain

Lymphatic pain most often occurs in the lymph nodes, a series of glands that produce lymph in the body. Lymph is a clear substance that is pumped through the lymphatic system to nourish tissues and return wastes to the bloodstream. Lymph nodes are under the jaw, armpit and groin, and behind the head, as well as in other places. Swelling or pain in these areas could mean a mild infection or even a life-threatening ailment.

Natural Immune Defense

• Lymph nodes are a major component of the body's immune system. If the body is under attack from a virus or bacterial infection, the lymph nodes may become swollen or tender as they are working hard to produce antibodies to stave off infection.

Tumors

• Pain in the lymph nodes may also be a result of a malignant tumor or growth near any of the lymph nodes or the early onset of Hodgkin's lymphoma. If lymph pain increases gradually or remains for an extended period of time, it may be a sign of a tumor as opposed to an infection.

Allergens

• Fungal infections such as sporotrichosis can also cause lymphatic swelling and pain. Cases of allergic lymphatic complications have been reported after patients received the smallpox, typhoid, measles, or mumps vaccines. Sulfa drugs such as iodine and penicilin may also cause side effects within the lymphatic system.
