Oh so sory to hear about your poor daughter,i got shingles about 3 years ago on my birthday of all times
I was told by the Dr to get some calamine lotion, you can get it in a cream now, but i was also told about some gel, or spray called Virasoothe,it is adverised mainly for children with chicken pox, but it was so much better than the calamine
The spray is handy as you don't even need to touch the skin, and it is very cooling and stops the itch
The pain is terrible, and can last quite a long time,it felt like kidney pain to me as the rash was in that area,
My Dr gave me Gabapentin as that is for neurological pain, but the dose he gave me made me feel dizzy, the lower dose is better
Hope she feels better soon,i think mine lasted about 6 weeks, gradually getting better, but i had numbness in that area of the rash for a few months
