Anecdotal, but this was my Dad's SSD experience. Didn't got to court, but had to get a lawyer involved and it did take over a year.
That being said, I just got my 100% disability, which was a shock. I can still walk (kinda), run (kinda) and lift heavy things (not overhead). But I hurt while doing them, and even more when it's done. Plus I'm about 5 years out from back surgery #3.
During the VA screening I moved until discomfort, and was honest about how I felt physically. Legit felt a mountain of stress come off when the doc wasn't fighting to give me more Vit M, more PT, another pain pill, etc. Took down my info professionally, gave me some old man advice (always appreciated), and was just chill.
After 21 years...I'm just looking for some chill at this point.
