I doubt anyone on this board could give you that reassurance. Since you used the word "MAY" I would feel comfortable telling you that this might happen. However, I would caution you that spinal surgery never promises to return you to the way you were prior to ever developing "back problems." If you are very lucky, you MAY end up getting some pain relief from the procedure.
I would also inquire if you have tried all other conservative treatments and have made every attempt to heal? Surgery, however "micro" it may be, should always be considered as a last resort. Back surgery is a bit different from other kinRAB of surgeries. There are so many nerves that feed into the spinal column and as a result, there are many things that can go wrong.
Surgery definitely has its time and place, but you need to be sure you have exhausted your other possibilities. Have you gotten a second opinion from another spinal specialist?
Some doctors are too quick to tell you how easy it will be and how fast you'll be able to get back to your normal level of activities and return to work. They make it sound like a simple procedure, particularly the "micro" surgeries. I guess for some people it does turn out to be relatively easy. But many others live to regret their decision. I'm not saying you shouldn't go ahead with it. I just want you to know what you're entering into, so you do it with your eyes wide open!!
