Denied for SSI

I applied for SSI cause my back. I have 2 missing vertbranes and no fatty tissue around one bone so my spinal cord rubs against it. Because I had moved from Ma. to Ar. and with no heath insurance, when I applied SSI sent for my medical records. They said my Dr never sent my records so went to see one of SSI Dr's. I knew I would lose right then cause he didn't take an mri or cat scan but a plain x-ray which won't show all of what's wrong with my back. I did lose they said I'm able to work. So been trying find work and put aside my thoughts of SSI doing an x-ray they knew wouldn't show the truth. I guess I'm more writing to tell people fight for your case I didn't and am so sorry cause I live on tylnol and advil and now fight with depression to try and get a job with some health insurance. Don't let a no answer stop you when you know your right.
