What can cause a canker sore on tonsil?
It’s excruciating, I know….well just more very unconfortable instead, more often it’s only a form of irritation in the mouth just caused by scratching it with a toothbrush or even food. Canker sores take longer to heal when they’re there too, like 3+ weeks, and sometimes the pain goes near the ear, but I wouldn’t worry unless it’s longer than a month or it’s debilitating, in which case make sure it’s not something worse.
