The lymph system is a network of lymph nodes, lymph ducts, lymph vessels, and organs that produce and move a fluid called lymph from tissues to the bloodstream. For more information on this part of the body, see lymph system.
Lymphangitis most often results from an acute streptococcal infection of the skin. Less often, it is caused by a staphylococcal infection. The infection causes the lymph vessels to become inflamed.
Lymphangitis may be a sign that a skin infection is getting worse. It should raise concerns that bacteria may spread into the bloodstream, which can cause life-threatening problems.
Lymphangitis may be confused with a clot in a vein (thrombophlebitis).
Symptoms
Chills
Enlarged lymph nodes (glands) -- usually in the elbow, armpit, or groin
Fever
General ill feeling (malaise)
Headache
Loss of appetite
Muscle aches
Red streaks from the infected area to the armpit or groin (may be faint or obvious)
Throbbing pain along the affected area
Signs and tests
The doctor will perform a physical exam, which includes feeling your lymph nodes. The doctor may look for signs of injury around swollen lymph nodes.
A biopsy and culture of the affected area may reveal the cause of the inflammation. Blood cultures may be done to see if the infection has spread to the bloodstream.
Treatment
Lymphangitis may spread within hours. Treatment should begin promptly.
Prompt treatment with antibiotics usually leads to a complete recovery. However, it may take weeks, or even months, for swelling to disappear. The amount of time it takes to recover depends on the cause.
