Does tonsillitis can cause swelling of lymph nodes?

Yes, tonsillitis can cause swelling of lymph nodes, particularly the lymph nodes in the neck. When the tonsils become inflamed or infected, they can trigger an immune response that leads to swelling and tenderness in the nearby lymph nodes. These lymph nodes act as filters, trapping bacteria and viruses, and they can become swollen as they work to fight off the infection. The swelling of lymph nodes is a common symptom of tonsillitis and typically resolves as the underlying infection improves.
