“Most commonly, the shingles rash develops as a stripe of blisters that wraps around either the left or right side of your torso.

“Sometimes the shingles rash occurs around one eye or on one side of the neck or face.”

Therefore, it is much more likely to affect older adults and people with weakened immune systems.
