Your right....it can be seen both ways. For me when I still had so much pain after my level 2 fusion on my neck and my spine doctor was so preplexed...he did the usual arm/pulse tests, but the weird thing was they were different each time. So for me I felt I needed more. But thank you for your response I have learned so much form this site and I appreciate everyone who takes time and pushes through the pain to write.....

Thanks
