A shingles rash on the buttocks first appears as blotchy red spots that turn into clusters of fluid filled blisters over the course of several days, says Everyday Health. Although the shingles rash usually appears on the buttocks or trunk, it can spread to other parts of the body.
Shingles blisters transition from clear to white and then yellow or bloody as the immune system combats the virus, explains Everyday Health. Within a couple of weeks, the blisters burst and create sores that form scabs. The scabs fall off within three weeks. Shingles causes pain and itching, and patients often manage the symptoms with non-steroidal anti-inflammatory drugs, calamine lotion, cool compresses and topical antibiotic ointments. Doctors can prescribe antiviral medications to reduce the severity and duration of shingles symptoms.
