With my trial I was given propofol so I felt nothing. Apparently they woke me up long enough for the Boston Scientific Rep to ask me questions about the programs she was setting and where I felt the vibrations. Then they put me back to sleep and finished the procedure. There may have been one or two stitches I believe, but it was minimal. I have had 5 previous back surgeries. I would definitely recommend the trial as it made a lot of difference in relieving the sciatica that I constantly have.
Best of luck in your journey 🌸
