Welcome to HCM.
I am suspecting herpes zoster
) in your case. You are right that shingles is a reactivation of chicken pox
which usually occurs in childhood.
This is caused by a virus which remains latent or hidden in the body and gets reactivated when the persons immunity gets low due to illness, increased stress levels etc. This reactivation is common in the elderly.
In your case I am suspecting exposure to the virus (your daughter) could have triggered the reactivation of zoster.
This infection presents with rashes on one side usually supplied by the nerves affected by the infection. This is called dermatomal distribution.
I would suggest application of acyclovir
cream over the lesions 4-5 times a day. Tab Atarax
25 mg thrice a day for a week for the itching.
