My 3 year old has somewhat of a rash on his belly and legs looks more or less like spots that were scratched at and have a little scab and he also has had a rash on his private areas for about a week now. The rash looks like little red dots all over. The day before yesterday his hand had some smaller white dots on it and we took him the the pediatrician and they said chicken pox. I’m not sure they were right. His had has gotten worse and his fingers are a little swollen. He also has bad eczema so I thought maybe the his legs and belly were eczema and he had a yeast infection before we took him to the doctor. Any suggestions? I am attaching a picture of his hand.
