Re: Allergy shots and canker sore on tonsil.. related?
I also think it's unlikely to be related.
The most common reaction to allergy shots is a bump/redness/itching near the injection site. Rarely, they cause sneezing, full-body itching or difficulty breathing. I can't see them causing just canker sores though.
Have you tried gargling with warm salt water? It works well when I get canker sores, and it's pretty harmless.
