1.What is it?
Tonsillitis is an inflammation of the tonsils which is caused by viral or less commonly a bacterial infection. At the back of the throat, tonsils are two lymph nodes – one on either side, which act as a filter in trapping the germs, which could enter through air and cause infection. Tonsils produce antibodies to fight against the infection, but at times they tend to get infected themselves. When infected they become inflamed, which is the condition known as Tonsillitis.
