oh my sympathy and prayers for you BIL. My Hub had them in 98 when florida had all the fires and he had them in his throat to top it all off.
Believe when i say i know what he is going threw. It is Way harder when one is older and can also lead to other things like t.n. and p.n. N=neuralgias in worse cases..... here I am probly making you feel worse and worry more but some may think chicken pox is nothing and they would be wrong! same with shingels they are much alike . You and your famliy have my prayers for the pox and shingels to pass safely and QUICKLY by and may both recover fully and fast with no one else comming down with pox or shingels
many prayers and blessings .
Peace Peace
