Overview
Lymph nodes may become swollen during a COVID-19 infection. They may be felt in the neck, underarms, or groin. This is a sign that the immune system is working to fight the virus.
Symptoms
Tender, enlarged, or firm lymph nodes. They may be painful to the touch. They are often one of the first signs of the body fighting an infection.
Causes
The immune system produces more white blood cells to fight the virus, which can cause the lymph nodes to swell. This is a normal immune response.
Treatment
Swollen lymph nodes usually resolve on their own as the infection clears. Warm compresses and over-the-counter pain relievers can help manage tenderness.
When to See a Doctor
If the swelling is severe, persists after other symptoms resolve, or is accompanied by fever and weight loss, see a doctor.
