I just spoke with the doctor. He cleaned up more disk. He found a little few fragments of disk and cleaned them out as well. He also found that Gabe's nerve was hooked to scar tissue. Every time he went to separate the nerve from the scar tissue Gabe's leg jumped. So a combination of the few fragments of disk and the scar tissue were causing Gabe the pain.
The problem is that there is no way to stop scar tissue from reattaching to the nerve. The surgeon cleaned out more disk in hope to prevent this from happening but only time will tell.
Now we wait for a hour, until Gabe starts to wake up then I get to go see him.
