I am buying a new thermometer because ours broke last week and we haven't gotten a new one. My 5 year old has been warm to the touch for a few days, she says his throat hurts, and his neck under his chin hurts, he says his tongue hurts, when I looked in his mouth, his tongue has white spots under it on the right side. this morning he said that a spot on his gums hurts too, I looked and it has a small sore there too. Any ideas? Should I take him in?
