On my 2nd day of chicken pox,I accidentally scratched 3 blisters on my face, each blisters twice and few blisters on my neck.Today i.e. 8 day, the blisters have dried up and brown coating have been formed. Today during sleeping​, I scratched one of those previously scratched blisters on my face as a result of which the brown coating came up. I am afraid that any of these scratched blisters might cause permanent scarring on my face or body.Please help me by telling whether scratched blisters will scar my face body or not. And if scar are formed what I should do to get rid of these as soon as possible.
