See a dentist to confirm that you have tongue ulcers. Typically a canker sore or aphthous ulcer will resolve within 2 weeks.

Two suggestions are first Homeopathic Remedy merc sol which is good for ulcers or any destruction in the body. And the other suggestion is putting ozonated olive oil on the ulcer a few times daily, or getting an injection of O-Zone into the ulcer that will get rid of it and get rid of the pain quickly

None, really. They should heal quickly on their own. If you get them often, you may have a folate deficiency. If they don’t go away you should go see a dentist.
