Well I'm not in any way medically qualified but I'm sure that's what HF&M looked like on my 2 DC. Actually, we renamed it Hand, Foot and Bum because they both had loads on their bum and all down their legs and feet but none on their faces/in their mouth.
Actually, they never went to the GP with it, it was me who 'diagnosed' as HF&M. I even got it myself.
They were both a bit grotty and miserable for a few days but that was it.
My twins have just come out in it - legs, bum, arms covered, some in & around mouth, nothing on trunk or hands! Both been miserable but well in themselves. Just have to ride it out (been a week since first twin came down with it and spots just starting clear).
Yup definitely think it's HF&M - my daughter has had it twice this year and it was really bad the first time, but over a lot quicker the second. Loads of spots/blisters on hands/arms, feet and nappy area.
The first time she had it (the unwellness) lasted for well over a week and she had the blisters/spots for a couple of months (fading slowly over that time). The her toe nails and skin around feet started to peel off :-( not nice, but didn't bother her.
