Hello-I had the Vertiflex implant procedure on May 28th. 9 weeks later I had the best pain free week in 15 years. It took a full 8 weeks before I felt comfortable. I'm now at 13 weeks and so far, so good with very slight pain. My right leg still goes dead occassionally and I have to sit for 60 seconds or so. I see the doc in early Oct and I'll need to confront the dead leg issue.
Best of luck to you.
