Welcome Scaredykit. I'm sure someone with experience will be replying to your post soon. Meanwhile, there is a thread titled Chronic Pain 101 at the top of the thread listings. The third post has a lot of good info about the type of surgery you are scheduled to have. I would suggest reading it.
Best of luck with your surgery and I hope for a strong recovery for you!
