Hi, I'm Maxine and have spinal stenosis, degenerative disc disease and spondololithesis. Having been very active and dealing with what I thought was just sciatica I spoke to my Dr. who ordered x rays and an mri afterwards which showed a 9mm slippage L4-5 and the pressure on the nerve which is why my leg goes numb when walking. I opted for decompression therapy, acupuncture, physical therapy, massage & reflexology but the intermittant pain is getting worse. I have a follow up appt. with the Neuro surgeon who suggested the big back surgery and said I wasn't really a candidate for the small one. What should I ask him about how to prepare before surgery and what should I expect after surgery? Thank you for your feedback.
