About 6 weeks ago I burnt the tip of my tongue with very hot tea but the disconfort on my tobgue has not left. Every few days I spot a red round light ulcer on the tip that goes away and come back after a few days. I also have waves on both sides something that appeared after 4 weeks. My dentist did not see anything unusual but sincey visit the tibglibg has never left, sometime on one side, or another or underneath or on the tip.
