I have had a back problem for a few years now - herniated disc kind-of between the shoulder blades. Anyway, the last couple of months I have been getting tingling sensations in random places for varying durations, and frequently on my face it feels like i have spider webs, and my nose feels like it has been punched all of the time. In the UK, the doctors don't want to know about Backs unless you are peeing your pants. Should I be worried? What can I do?
