I have had geographic tongue most of my 56 years. A dentist made a recommendation which has been very helpful in treating the discomfort. I keep liquid Pepto Bismol and liquid Benadryl on hand. At the first sign of patches and pain I take a swig of each, gargle and swish it around in my mouth, then spit it out. It really works instantly in minimizing the pain and seems to help "heal" my tongue more quickly than doing nothing at all. I do this as often as necessary during the day, it provides very soothing relief. Hope this helps somebody with this weird and annoying problem.
