Floorman,
It's hard to say. Given you have been working for 33 years I assume you are in your 50's. That is primetime for OA--your hormonal levels are down so your body doesn't repair itself as well. You could look into HRT (test, HGH) or if that's too risky get some joint injections of PRP, stem cells or HGH.
See your doctor and see what he thinks. They could check for OA with x-rays and then an MRI for details.
My guess is it's too early to tell but OA would not be surprising.
