Lymphadenitis

Lymphadenitis is the inflammation of a lymph node. It is often a complication of a bacterial infection of a wound, although it can also be caused by viruses or other disease agents.

Causes

Bacteria are the most common cause of lymphadenitis, but it can also be caused by viruses, fungal infections, and parasites. Other possible causes include allergic reactions, autoimmune diseases, and certain medications.

Symptoms

The symptoms of lymphadenitis can vary depending on the cause and severity of the infection. Common symptoms include:

• Swelling and tenderness of the lymph nodes
• Red, warm skin over the lymph node
• Fever
• Night sweats
• Fatigue
• Weight loss
• Infection at the site of the lymph node

Diagnosis

Diagnosis of lymphadenitis is usually based on a physical examination and a review of the patient's medical history. The doctor may also order blood tests, imaging studies, or a biopsy of the lymph node to confirm the diagnosis.

Treatment

Treatment for lymphadenitis depends on the cause of the infection. Antibiotics are usually prescribed for bacterial infections. If the lymph node is abscessed, it may need to be drained. In severe cases, hospitalization may be required.

Prevention

Prevention of lymphadenitis primarily involves good hygiene practices to avoid infections. This includes regular hand washing, avoiding close contact with sick individuals, and keeping wounds clean and properly dressed.
