What are throat white patches?
White patches at the back of your throat or on your tonsils can be signs of infection. Usually these patches are irritating or painful, and sometimes the pain is worse with swallowing or on coming into contact with acidic foods. In addition to infection, sometimes these white patches can be a result of an injury from chemical exposures.
