Congratulations on your successful surgery. Whatever pain you have will be very short in duration. I had mine put in almost 10 years ago. It went off big time 5 years ago and the result is, well I am able to sit here and write this post.
I am on my 2nd one now. After all these years I don't even give it a 2nd thought.
I hope it serves you as well as mine has done for me.
