Saw the nero surgeon

Well i Saw a Nero Surgeon yesterday. After looking at my MRI he said that i am very close to be in a wheelchair. My back is not from my ms, but he says it is affecting my ms because of the stress. He was so mad that nobody did anything about my last mri from 8 months.because he said my spinal stenosis is very bad and he has saw some bad backs but mine was one of the worst he has seen. He said he is hoping there no permanent  nerve damage. He really wants to do surgery and said he would help me get disability. So i don't know what to do. how to even get started.  Thanks Nancy
