For the last week, DH and our two pre-schoolers have had terrible sores in their mouths. Not quite like usual mouth ulcers - their tongues are bumpy and the roof of their mouths is red and spotty. DH says he has a smokey taste in his mouth too. This morning my tongue is tingling and I've got a bitter taste in my mouth, so it looks like I'm next! No other symptoms whatsoever, so I don't feel like it's something to bother the GP about. The DC have both improved quite a bit over the weekend, or I was going to call today. What on earth could it be??
