I have applied for disability and they said my paperwork was at the medical review board, what does that mean? what are my chances of being approved, i have had 4 back surgeries and not able to work.I am in pain at least 85% of the time, and the Dr. said I have nerve damage, and wants to do nerve blocks,on T-6 to T-10 of my spine, do I stand a chance of getting SS?

I have been out of work 2 1/2 years, and this is my second time to apply.
