Im 34yrs & 15days back my wife had Shingles on her neck n ear. we had sex twice when she was taking medicines n now I have got chicken pox all over my body.

kindly suggest how many days it would take to cure? Doctor had suggested listed medicines-
Valtoval 1000mg
Neurobin
Calpol

Also using calasoft on blisters. now blisters are seen on penis foreskin & shaft too..I'm worried will it get cured?
