I am researching long term discharge on one side of my tonsils. A GP said it was related to "food" and nothing to concern myself about. I also have a large, old uncapped filling on that side from a root canal, plus a problem with the ear on that side. The ear is always itchy. Apparently there is a nerve near the tonsils that can be irritated by large pieces of hard pus. I am an extreme allergy sufferer also.
