question: I was travelling for 3 days last week and could not find space for bath. After that (Four days before) I started itching on some parts of my body chest area perhaps and unknowingly I scratched, upon which I found the next day it s like a ringworm, round shape rashes. It spreads also first just like a pimple that itches and then becomes bigger and round. I was using itchguard for last 4 days and I can t make out it s better or not. Is it okay to use quadriderm RF. Kindly suggest me.
