Hi Kristie,
I just saw your post and wanted to also say "Welcome". Apart from visiting the forum that Curious posted, I just wanted to say that I know there are a few people who use these forums who have experienced Shingles, or have family members who have in the past, and hopefully they'll also be along to give some advice.

All the best to you and your brother. I hope you find some answers and some relief.

take care,
Lara
