Eric, when my sense of taste returned and I began to eat real food (what a joy!) I repeatedly burned my tongue with food that was too hot. It has only been in the last few weeks, 18 months out, that I can drink a hot cup of coffee or enjoy a hot bowl of soup. As long as you and a doc are watching the spots, I don't think it is anything to lose sleep over. Just another rad after effect, and some people have many. You are doing well.
