Both wrists shot after 15 years of meat cutting

I honestly don't even remember what it feels like to wake up without my hands hurting anymore. I've been a butcher at a market over near Greenville for a little over fifteen years and the last three or four have been brutal on my wrists. Constant cutting, twisting, lifting heavy primals, all day on my feet with a knife in my hand. At first I just wrapped them with ace bandages and powered through, but now I've got shooting pain up both forearms, numbness in my fingers, and my doctor says it's severe carpal tunnel in both wrists along with tendonitis that's probably going to need surgery on at least one side. I finally brought it up to my boss because I can't keep working at the pace I used to and he basically told me that's just the job and maybe I should look into a different line of work if my hands can't handle it anymore. No offer to help with medical stuff, no suggestion about filing a claim, just basically saying it's my problem. I've been reading up on it and I know repetitive stress injuries are supposed to be covered under workers comp, but I also know they're harder to prove than something like a fall or a cut. My wife is pushing me to stop waiting around and actually do something before I lose all function in my hands and can't work anywhere, not just this job. She found a repetitive stress injury lawyer Greenville NY who she wants me to call but I guess I'm still in that mindset of thinking maybe I just need to tough it out a little longer. Has anyone here actually gotten workers comp approved for something like carpal tunnel or tendonitis from a job like this? I feel like my boss is going to fight it tooth and nail and I don't know if I have the energy for that kind of battle on top of dealing with the pain every day.
