What can this be? Chicken pox?

Quasia

So my daughter has had an itchy bag she always does. So I didn’t think anything of it. She has bumps on her back but I don’t think it’s that bad. But today her father noticed that she had bumps and marks on her feet and he said it could probably be chickenpox. I didn’t think about that until he said it but now that I look at it I wonder if it is hand foot and mouth disease. I have to take her to the doctors but what do you think this could be? I haven’t had chickenpox since 98 so I don’t remember what it looks like.
