Hello about a month ago my back started to hurt at first it was a dull ache and steadily grew worse I finally went to the VA emergency room only to find out is that my muscles are spasming and pushing on my sciatic nerve due to a medical condition that I did not know I had. The doctor explained to me that my condition only affects about 2 to 3% of the world's population. What I have is a missing L5 lumbar as well as a completely fused L4 to S1. I cannot find any research for this specific issue just for one or the other. I am contemplating buying a back brace or trying to find any other options that could help with the issue any advice would be helpful. And if you know the name of this condition that has both these issues in it please let me know so I can fully research what is wrong. Thank you for your time and have a great day
