I took Levaquin for 3 days and noticed a cluster of blisters on my left hand. My doc told me it is shingles.?

The cluster of blisters turned into one large ugly bluish red outlined blister. I only have one other small area on my left arm. could this be from the Levaquin 750mg? The hand blister started the next day after the first dose of Levaquin. Would Levaquin induce the shingles?
