Can Allergies Cause Swollen Lymph Nodes
Medically reviewed by Dr. Mandy Liedeman

Key Takeaways

  1. Allergies can lead to swollen lymph nodes due to the immune system’s response to an irritant. 
  2. Allergies, including seasonal, food, and skin allergies, can cause watery eyes, itchy nose, sneezing fits, runny or stuffy nose, and rashes or hives.
  3. Pollen allergies typically do not cause swollen lymph nodes, but in rare cases, severe allergic reactions in adults and children can result in lymph node swelling. 
  4. Sinus infections and asthma may also cause swollen lymph nodes.
