don't let numbness hold you back, I broke my back about 10 years ago and severed 5 nerves on my left side and severely crushed my sciatic nerve, at the best of times I can feel my big toe and inside of my heel, at the worst of times I can't feel anything below certain parts of my hip and thigh.
I still try to get out and paddle when I can, but now I use a "sherpa" (usually my daughter or son in law) and a canoe cart, the biggest hassles are 1) walking in the dark or low light- I now use 2 headlights (one around the neck) to illuminate the path and the ground because I discovered that without sensations you can't tell where your foot is or if the placement is stable, 2) my balance while standing is next to zero, but sitting in the canoe is no problem and I can rotate my pelvis and hips normally, the biggest problem 3) is getting in and out- for decades I've dispensed with placing my paddle across the gunwales and just stepped in, now I'm back to doing it the conventional way to add that third point for stability. getting out is a whole new ballgame- if there's a high enough dock or rock it's simply a matter of swinging my butt onto it , scooching back and standing up. Beaches sometimes require me to pull up parallel to it and log roll out, which often leaves you wet and sandy. The worst are low floating docks that move under you, essentially meaning you have to roll out, belly flop onto it, then crawl off because standing on a moving object is a no-go...
Everything is still doable, just in a different way, and I learned a very valuable lesson- carry a gallon of water and a change of clothes in the car- driving home covered in cobra chicken droppings is not good for either your sinuses, upholstery, or travel mates...
