Going on three weeks now, thought the pain in ear and teeth was a sinus infection. Turns out its looking like my shingles has reactivated and gone into my inner ear nerve. Completely deaf in left ear. Stabbing pain in ear and jaw seems to be the give away to shingles. No blisters though, although now my back is getting sore where I had the shingles last time. Pain is soooo stressful.
