I am also having tingling in my back below my left shoulder blade towards the middle of my back. I have had shingles in the past but directly on the other side. This isn't the same thing. It's been going on off and on for about 2 years. I was in a car accident back then and I believe it's related to that. After many months of chiropractic care, massage, and physical therapy, I think this is just something I'm going to have to live with. At least there's no pain associated but it's still bothersome!
