i have cracks all over my tongue. this problem had just sprung up. it has to be some kind of deficiency in my system. i've been to my doctor and to a ENT. my doctor didn't know. the ENT said he thought it was normal. well i don't buy that at all. i know an older women who had what she said was worse cracks in her tongue than mine. her doctor at the time put her on either a prescription or herbs or something. she can't remember because it was so long ago. but her tongue went back to normal after she took whatever it was. her doctor has long since retired, may even died by now. but i'm still stuck with the condition. does anyone having any knowledge of this or someone else that has it? and what can possibly be done to return it to normal.
