    The bottom photo is a person with a geographic tongue. I have it and it can be so painful, it’s can be caused by eating certain foods eg spicy, or sour foods. Unfortunately there’s not any treatments and it should get better on its own 🙂 x

    Might look up ‘Geographic Tongue’. This is a benign problem that comes and goes. No cure. However you can find a list of foods etc. that irritate the condition. Had it for years, mostly inconvenient and irritating.
