My mom has had shingles 3 times in the last year, all in the same place. Now they are on the other side of her abdomen as well. What can we do?

Unusual. It's unusual to get repeated outbreaks of shingles. Sometimes cutaneous herpes simplex can be confused with shingles. It looks very similar, but is usually less extensive. If there's any doubt, a culture or pcr from the blister can make the diagnosis. Either way, the treatment is the same: chronic suppression with daily valacyclovir.
