Hi Kathy, and welcome to the board!
We're not doctors, but we all have back problems of various types, and many of us have had fusions. We can share from our own experiences and try to answer whatever questions you have.
As far as the pain meRAB, there are others out there. Make sure your doctor knows the reaction you had last time. I'd put that at the top of your list of questions. Ask him what alternatives are available for pain control. Some other questions you might want to ask: will he use BMP (a protein matter that helps to stimulate bone growth), will he use your own bone from your hip or donor bone, will you have a brace after surgery, will you have a walker, are you allowed to go up and down the stairs, how long to not drive, how long for your husband (if you're married) to "leave you alone", will he use staples or stitches, and will he approve temporary handicapped parking for you (look at your local DMV's website for the forms -- it's very helpful when you need to be able to open the car door wide to get in and out).
I don't think they use much other than titanium anymore. When I asked my doctor what kind of metal I had in me, he said it was mostly titanium. I guess there are bits and pieces that aren't, but I don't know what from the x-rays. It all just looks white.
I don't have diabetes, but I do have a son who's a type 1, and we've been told that if he gets a major illness, to just keep testing regularly even if he isn't eating at all. You know that anything out of the ordinary, like illness or surgery, can affect your glucose levels. How was it last time? Did your levels get off very much after surgery and during recovery? Did you feel like you had it somewhat under control? I know type 1 is completely different from type 2, so I really hope you find another type 1 you can talk with. My son gets so frustrated when his grandma, who's a type 2, tries to "help" him to take better care of himself by eating right, etc. She just can't get that he isn't diet controlled. He thinks he has it easier than type 2's because even though he has the more serious type, he can eat whatever he wants. He just takes whatever insulin he neeRAB to cover it. I know there are some type 2's here on the board (and I'm not saying that what they deal with isn't serious), and I hope some will chime in even though it's different. There are still some similarities, too. (You all have sore fingertips! Except my son. He hasn't tested on a finger in two years except at a doctor's appt!)
Read the sticky at the top of the page called "post surgery tips." It has a wealth of information that will help you prepare. My best tips: get a satin-type bottom sheet for your bed and slippery pj's. You'll be able to turn sooooo much more easily, without nearly as much pain. I took off the top sheet, though, and put the cotton one back on. The satin one slid out from being tucked too easily, and I couldn't get it back myself after surgery. And get yourself a good quality grabber tool. You'll use it regularly! It will be worth it's weight in gold your first day home!
I would get a second opinion for your peace of mind. You have a few months yet, so you have time. Are you comfortable with the doctor you have now? That's very important, to have a good trust level with him. But I would still get a second opinion anyway, from a doctor is a different group.
I hope this surgery will be exactly what you need and that you'll be back to your old self after some recovery time.
Take care,
Emily :wave:
