Since as far back as I can remember, I've had a tongue that has a whole bunch of cracks on it. It has a pretty big one right down the middle, a bunch of little slits on the sides. When i was born the Doctor told my mom that I have a geographical tongue but I've looked up what a geographical tongue is and realized that at one time I had it but not anymore. Now it's just a bunch of cracks. There isn't anything on any website about a cracked tongue so I wondered if anybody can tell me why I have it or much less anything about it at all.
