many people get canker sores. aphthous ulcers. this is not a sign of anything bad or ominous. they should resolve spontaneously in a week or so. if not you will need to see your medical provider for an examination.
i have three canker sores in my mouth is this a bad sign? . there are 2 on my tongue and one on the roof of my mouth in the back and i also have a bad sore throat. its been like this for 4 days and its very uncomfortable. could it be a sign of something worse than just canker sores?
