The AN side of my tongue is numb also. It feels like I burnt it on something hot, especially on the side of the tongue but not to the point of being painful, just to the point of I know it's there. I had this before the GK, and it is still there. I remember telling my dental hygenist about this on a checkup, 6 months ago. She must have thought I was nuts, and this is because these symptoms, at least for me, have been so hard to explain. So, now that I know more, I guess the nerve endings are creating the feeling that something is seeping into my mouth on the left side - like sinus drainage, or tears and this creates, also, a kind of taste sensation. She checked me over for any damage and found nothing, because I told her I didn't want this "drainage" to be ruining my teeth. So, I have my next dentist appointment next Thursday (also hair and doctor appointment - busy day!) and I can tell them, now, WHY I had all this going on. I have, thankfully, not lost my ability to taste things, but I have noticed that some tastes are different, or diminished, or changed. Perhaps I am only tasting things on the right side now. I had some Bread and Butter pickles and I don't think they tasted as strong to me as before. That's when I thought, maybe something was different. I hope it goes away, for both you and me!!
