Looking for anyone that has had experience with this surgery. Please share.

A little information about me. I am a 53 year old male. I've been experiencing sciatica in my left leg for 4 years now. In year 3, it got to the point where it was unbearable. My neurosurgeon performed a MD surgery on me.

1 year later, a lot of the Sciatica has returned, although it's not as bad as the first time around. I can get relief via walking or laying on my stomach with a pillow under my chest. My neurosurgeon says the MD was a success, but I have some impingement on my nerve and wants to do this surgery.

Has anyone had this surgery? Warnings? What to expect?
