How long have you had these symptoms? If it is just today, and you DO develop blisters, it could very well be shingles. Sometimes shingles doesn't show blisters right away.
If not, I would look into possible systemic infections, or yes, viral infections. If the symptoms last longer than a couple days, it merits a trip to the doctor.
Please let me know if I'm off the mark here, or if you have more questions. I can do more research.
