How does the rash spread across the body?

A shingles rash tends to center in one dermatome, but there may be odd blisters in an adjacent area if the branches of the spinal nerve cross into a different zone.
In the 1–2 days before the rash appears, people will experience burning, tingling, or pain on the area of the skin where the rash develops. This is because the virus stimulates the nerve as it travels along its pathway.
