Is it hot where you are? I get that sometimes when its hot out. Look up heat rash on google and click on images, kinda looks like that (and chicken pox, and... who knows)

Itch cream/calamine lotion... See a doctor if the itch cream and stuff does not work in a few days!...

Some people who have had chicken pox before can get it again, especially if its that bad that you still have scars!...

What places has your mom and you been that would have had those spots arise?
