TL/DR, daily life presents close to zero limitations, training can be cumbersome or require adaptations to some lifts and can cause a constant, low key aggravation.
I regained 97% mobility after physical therapy. Inflammation from weight training reduces that mobility, but I couldn’t give an exact degree of difference.
I have a hard time fully supinating the hand on my injured arm (I think supination. Turning my palm up). To the naked eye and for 99% of daily activities it’s not noticeable or limiting. No issues otherwise.
Areas of concern are getting change at drive thru windows if I use cash, mixed grip deadlifts (I refuse to train them this way without being able to flip over/under hands for balance) and I’m pretty sure pressing.
I can press but it legitimately hurts as i get heavy and I always feel like there’s still some gas in the tank even after my body shuts down the movement due to pain. Sometimes curls if I’m heavily rotating the dumbbell and I can’t do straight bar, but knurl bars are fine. I do a lot of knurl bar curls, hammer curls, drag curls and spider curls as these don’t cause unbearable aggravation.
I’m used to the constant background aching at this point, and am aware it would go away if I quit lifting.
I compete casually in powerlifting for the record. And I’m no Ronnie Coleman but when I show up in a group of normies and casual exercisers I get the side eyes, stink eyes, people standing taller or holding their arms out et cetera for absolutely no reason.
Elbow sleeves and wrist wraps help me a lot, and increased blood flow and stability would probably help your arthritis too. I wear sleeves for an entire workout, not just specific lifts and wraps for pressing.
Old fashioned balm goes a long way, ice packs and heat intermittently too. I do take anti- inflammatory supps annd occasionally smoke a little weed but avoid regular NSAID or prescription painkiller use. And I highly recommend a Rollflex forearm massager and regular stretching/mobility as I will occasionally tighten up and then other parts of my body begin to overcompensate.
It sounds worse than it is. I think stretching, mobility work, heat/cold and massage should be in everyone’s repertoire anyways.
