question: About a month ago I began getting a feeling on my back, right shoulder blade like an electrical current. It is quite annoying and I m not sure how to treat. About 12 years ago I had a neck fusion C-6 and C-7. What s going on? I am 60, work with special needs kids and stay active. Could it be that our freezing cold temps, for about a month, have something to do with this? Thank you.
