Unlikely: A true canker sore is a local auto-immune condition that results from different types of stress. It usually doesn't "spread" as you describe. If you have large patches in your mouth that are ulcerating, then that is indicative of a larger systemic auto-immune problem. Otherwise, you likely have a pharyngitis that is unrelated to the canker sore. Either way, you should see a physician.
