My 3 year old has been complaining off and on of tongue pain over the past two weeks. A few nights ago, he woke up in the middle of the night crying, saying his tongue hurt. He went to the pediatrician yesterday who could not find anything in his mouth that would cause pain. Just a few minutes ago, he began crying in his sleep and woke up screaming that his tongue hurts and didn t even want me to touch him. He finally pointed to the tip of his tongue for me, but I didn t see anything suspicious. He did let me look in his mouth, and there are no blisters or sores that I could see. He has not run a fever for any reason in months. I m lost as to what this can be. Any ideas?
