Denied after cervical fusion and posterior corrective surgery?

Hi support.Inmy mid 40s.Today I received a denial letter, I had a ton of documentation,and was just denied. They never sent me for an exam after a cervical fusion from failed surgeries. I had to go on to have a posterior corrective surgery the brushed aside all of my major points, i feel so much resentment right now I can’t foot my bills or afford a lawyer now. any one going through?any help with a pro bono?
