My tongue feels like i've burnt it?

Perhaps: Perhaps you did. Without actually seeing you, we would have no way to know. If that's what happened, it will resolve on its own rather quickly. If it persists or you want to confirm your own diagnosis, then you will have to see your own dentist. Feel better.

Tongue Sensations: Sometimes we do burn our tongue when we eat particularly hot foods, like pizza or baked potatoes, too quickly. That sensation can also be caused by eating very spicy foods, such as peppers . You should explore these, as well as burning mouth syndrome with your physician of a qualified oral and maxillofacial surgeon. You may also want to check for "adverse reactions' related to the meds you take.
