Take lots of fluid diet..

Thanks for the query. You should meet a Dermatologist for sure and initiate on appropriate treatment as early as possible. There are effective treatments available to reduce pain and dryness . Considering the above facts delaying consultation is not advisable. Other family members who never had chicken pox should be advised to refrain from close contact with affected member or isolate the affected member as it can cause chicken pox in others. Hope it helps you.
