I have headache, body ache, hot flashes, chills, pain radiating from my right hip and a rash on my right buttock. I was thinking maybe shingles?

Sounds right. Those sx would be suspicious for shingles. Treatment should start within 3 days of seeing the rash for best results. Anti inflammatories and topical creams prescribed by your doctor can also help. Fresh blisters and until they crust over can be contagious so be careful.
