It looks like an ant bite to me. I've only seen hand foot and mouth with multiple blisters
Not just one.

@elliotsmum, wouldn't hurt to see doctor just in case! They told us there is nothing we can do and it takes 7-10 days. She had fever her first few days and had a sore throat (no blisters). Does your boy have a temp?

@masseymomma16, guess we’ll be taking a trip to the doctor! Looks the exact same lol

That's what my daughters looked like! They soon turned into more blister like.

@mommytotheo, it’s just this one spot. I can’t get him to hold still to look in his mouth

Is it all over or just that one? There is a viral infection going around similar to hand foot mouth. My son has it.
