Welcome to practo.. The red lesion can be an ulcer. It's getting subsided .. Don't worry.. I advice you to avoid hot and spicy food. Do not touch the lesion or redness spot with your tongue or finger. Take more fruits and drink more water. Apply coconut oil in the red spot. Continue the remedies I said, and the redness will gradually subside. If the lesion didn't subside or it's increasing in size or increase in redness, Consult me. Thank you.. Have a nice day..
