I would just make sure to ask lots of questions and be very honest with them and yourself. And have them really explain things to you. I should have made the doctor explain his decisions more to me. Like why he took them out! Write things down! It is easy to forget. Write down how you are feeling a couple days before your trial..where your pain is, how intense, what makes it worse or better, what is hard for you to do, etc.. I wish I would have done that so I would have been able to compare while I was on the trial. I had such a hard time with pain in my back that it was hard to tell how my leg was doing. But I guess not everyone has that much pain in their back. Others could see a difference but at first I couldn't. Be VERY careful! Take lots of rest the first couple days to give the leads some time to heal. Then test it out. Go on light walks or whatever so you can tell if it works or not. I never had the chance to do this. I did get to walk a couple blocks (which I haven't been able to do in almost a year!) and it was awesome! Anyway, that is some advice that I can give you based on my experience. If you have any questions or what to know anything else just let me know. I would love to tell you. I wish you the best of luck!!!!
