I've had two major back surgeries.I am fused from l2 down through S1. I've done really well for the first three years.And now, this past year, i've had pain and numbness in one leg. I've had 2 MRI 2 EMG in 2 steroid injections. Still, no one can tell me what is causing the pain. Gabapentin doesn't really help. Now I am being told the only option I have is a spinal cord stimulator. Does anyone have an experience with that?
