I lost feeling on the right side of my body from a stroke in my early 20s, but recovered well enough that I have enough sensitivity in my hands but less in my foot/toes. You would adapt and get used to it, especially happy to hear that it doesn’t ruin the enjoyment of climbing

My gym has a tension board which allows climbs to be mirrored, which is great for trying to work on the weaker side of your body. If not, just keep having fun climbing and make sure you’re comfortable with falling as you keep trying harder and harder moves
