Tonsillitis

Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat. Signs and symptoms of tonsillitis include swollen tonsils, sore throat, difficulty or pain with swallowing, and tender lymph nodes on the sides of the neck. Most cases of tonsillitis are caused by infection with a common virus, but bacterial infections can also cause tonsillitis.
