Oh my...please go speak to someone who can help you with your worries. You really do not want to fall into the dark, lonely hole of illness anxiety. Yes, you are most certainly correct, tongue pictures are gross and unnecessary. No one is going to look at these pictures and suddenly say "Oh, he is right! He does have ALS!". You have your health, yet you are here, asking terminally ill folks and their exhausted caregivers (I was up for three hours with my PALS overnight), to hand hold your anxiety and obsession with ALS. Do you see how that sounds? Pretty self-absorbed, doesn't it? My apologies for being blunt, but your posts asking the same questions again and again are enough at this point.
I sincerely wish you the best getting the help you need. That help will not be in the form of another EMG or neuro visit, but will most likely be in the form of a professional to help move you past this phase you are going through.
Take good care.
