Most Tonsillitiss are called by tonsillitis. Tonsillitis is an infection
or inflammation of a tonsil. Sudden tonsillitis is often caused by a streptococcus
infection. It is marked by severe sore throat, fever, headache, malaise, difficulty in
swallowing, earache, and large, tender lymph nodes in the neck. Sudden tonsillitis may go
along with scarlet fever.
