Hi, my mom has developed rashes on the back followed
Continue with antivirals,calamine lotion
Welcome to ask a doctor service
I have gone through your complaints and reviewed the attached photograph.
Chicken pox usually takes 10-15 days to resolve.
Antivirals hasten the recovery of chicken pox which she is already taken.
She can apply calamine lotion on the affected areas twice daily.
This will reduce the irritation and itching.
I hope to have answered your query and would be happy to answer any further questions.
