There is all kinds of info out on the net regarding referred pain from discs and spinal alignment issues. I've never been able to sift through it all and fully understand whats being said since a lot of it is contradictory in nature, but I've also heard from medical types that doctors don't really know all there is to know about these things. Has anyone mentioned a pain management doctor who does spinal injenctions? These can often confirm different diagnosises that other tests can't, in the hands of a skilled anesthesiologist. The facet joints along the spine can be a source of nerve irritation and pain. Can you run this by one of your providers?(again, I'm just a patient)
