yes it doesn't always consist of blisters
can shingles rash not have blisters. my boyfriend has had shingles before but this rash he has is very large from his groin to all the way down his inner thigh on one side. it is red and blotchy on the outside of the rash but the red blotches on the inside are very light. no blisters and apparently has had this rash for over 6 months.
