What make your tonsils swell up?

Swollen tonsils, or tonsillitis, can be caused by viral infections, such as the common cold or influenza, as well as bacterial infections like strep throat. Allergies, irritants like smoke or pollution, and certain medical conditions can also contribute to tonsil swelling. Symptoms may include sore throat, difficulty swallowing, and swollen lymph nodes. It's important to consult a healthcare professional for a proper diagnosis and treatment.
