My son is 3 1/2 and started with a reddened area on his hand last night and woke up with these lovely blisters this am...any ideas? He also has 3 tiny ones on the back of his forearm of each arm. Very strange. Doc tried to tell me it was Chicken pox (over the phone diagnosis)I am thinking he got into something, he is always out "picking flowers". Any ideas would be great. Thanks
