Thank you for your query.
It is very difficult to advice over the possible cause without having a look at the lesions. Chicken Pox
are usually associate with fever followed by a rash. Herpes Zoster
usually involves a nerve
distribution and is very painful which is not in your daughter and your case. I suggest you consult your doctor who shall examine the lesions and advise you accordingly.
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
