Pictures of swollen tonsils can be found online at the official sites of WebMD and American Family Physician. A condition called tonsillitis, which is caused by a bacterial or viral infection, leads to swollen tonsils, according to MedlinePlus.
Tonsillitis usually produces symptoms, such as difficulty swallowing, sore throat, ear pain, fever and headache, states MedlinePlus. Treatment may include antibiotics, drinking plenty of fluids or gargling warm salt water. If tonsils are swollen in the absence of other symptoms, treatment is typically not prescribed, but further follow-ups with a doctor may be necessary. Removal of the tonsils is considered for people who experience recurrent tonsillitis.
