Lymphangitis is an infection of the lymph vessels (channels). It is a complication of some bacterial infections.
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.
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 or soft tissue infection is getting worse. The bacteria can spread further into the blood and cause life-threatening problems.
Symptoms may include:
- Fever and chills
- Enlarged and tender lymph nodes (glands) -- usually in the elbow, armpit, or groin
- General ill feeling (malaise)
- 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
Exams and Tests
Your health care provider will perform a physical exam, which includes feeling your lymph nodes and examining your skin. The provider may look for signs of injury around swollen lymph nodes.
Lymphangitis may spread within hours. Treatment should begin right away.
Treatment may include:
- Antibiotics by mouth or IV (through a vein) to treat any infection
- Pain medicine to control pain
- Anti-inflammatory medicines to reduce inflammation and swelling
- Cool compresses to reduce inflammation and pain
Surgery may be needed to drain an abscess.
Prompt treatment with antibiotics usually leads to a complete recovery. It may take weeks, or even months, for swelling to disappear. The amount of time it takes to recover depends on the cause.
When to Contact a Medical Professional
Contact your provider or go to the emergency room if you have symptoms of lymphangitis.
