Chicken Pox? or H,F and M?

A girl from mum's group same age as my DD has been diagnosed with Hand , Foot and Mouth disease. So I took my DD to docs yesterday just to check and he said she was fine.

This morning she has woken up with rash over forehead, cheeks and chin and even into the hairline. There are no obvious blisters - more like spots that seem to be getting worse as day goes on. She isn't obviously scratching but had got a couple of scratch marks on her face. She doesn't have a fever and is generally happy other than waking because of teeth.

I rang the Health nurse hotline and she seems to think it's not HFM disease cause its in more places than mouth and cheeks and thought maybe chicken pox. I'm going to docs this arvo but just thoght I'd see if anyone else knows anything about these issues!

We've had hand foot and mouth (both have had it). DD1 had it only in her mouth. Hundreds of blisters, it was awful. That was the worst becasue she couldnt' eat for a week. But apart from that no other symptoms.
DD2 had blisters (if you look closely they were puss filled) on palm of hands, fingers, and bottom of feet. She also had a few on bottom area. Nowhere else. I don't think HF and M is anywhere else. Im not totally sure about chicken pox, but I thought they kind of looked puss filled too?? Good luck and hope it goes soon .xox
PS If it's hf and m at least it doesn't really cause any probs, maybe slight temp. NOt itchy or anything xo
