Update: got a decision
I just got the denial in the mail, and I am so angry at their reasoning. Their reasoning, after the long list of physical issues I have, I can work with my knee issues. Yep, of all the things that were listed- torn meniscus that requires a full knee replacement, spinal stenosis, multi-level disc degeneration, herniated discs, arthritis in both knees, fibromyalgia- the one thing they focused on and claimed was my primary issue was knee issues: arthritis. So that is their reasoning for denial. I provided pages on how all these issues limit my daily activities, my ability to function, and how it affects me physically overall, and it seems like they didn't even look at that. I got a lawyer to help with my first appeal; wish me luck!
