Lap Band fueled by disabling injury?

Hi Everyone! I have reading through a lot of great posts with some great information from all of you, but I didn't see any relating directly to weight loss for injury relief. I was advised to have the Lap Band done do to severe back problems. I have tried many, many diets and have lost but then gained back and in some cases, more than I lost. Because of my injury I am limited to exercise and battle creeping weight that has been added since the injury. I was curious how many others are having or have had the same experience that I have had. How many of you have chosen Lap Band as a weight loss alternative to help alleviate pain and or help with it? How many have already had it done and have already started seeing good results on your problem areas? I would love for any of you to write in and share your experiences (good or bad) with me on this topic. Thanks for you support.
