I am HORRIBLY Bulbar -- and have horrible allergies. My allergy doctor looked at my tongue over 30 years ago and FULLY expected to see a geographic tongue. Close to 99% of his patients HAD geographic tongues. I was the RARE bird who had a normal tongue. Everytime I visited his office, I had to stick my tongue out for everyone to see -- such an oddity I was. Anyway, my tongue is STILL normal -- even though I choke, slur, gag, can't whistle, can't move food around my mouth effectively. So, I'm not really sure if the appearance of your tongue is connected to the severity of your MG. OR, maybe once again, I AM THE ODDBALL!!
