Tonsillitis is an inflammation of the tonsils that are present at the back of our throat. Tonsils are a pair of two oval-shaped pads that are lumps of tissue located on each side at the rear of the throat (pharynx). There is one tonsil on each side. They are composed of soft tissues that are similar to lymph nodes. The tonsils are a part of the lymphatic system that is responsible for fighting infections.

Tonsils can vary hugely in size and are susceptible to inflammation as they swell up in response to infection. Most cases of tonsillitis are caused due to infection from a common virus. However, sometimes even bacterial infections are responsible for tonsillitis.
