Seven years ago I had L5-S1 successfully fused, one year late I had L4-L5 sucessfully fused. Things have been going well enough since my two surgerys, but now I am getting left leg calf nurabness and both of my feet are nurab. I hate to go back to the surgeon, he has done pretty much all he can do. Does anyone know if L3-L4 would cause leg and feet nurabness. Although I have no bad backpain, I have some stiffness and pain about the L3-L4 level. I know it could also be scar tissue, but I cannot find any info on how long it take to grow the scar tissue.
