What do you do when you have worse hand-pain after a short use of cane or walker than improved knee/hip/ankle trouble with the aid? Especially since the hand pain doesn't abate for a long time of avoiding the aids?
Knee scooters, mobility devices, wheelchairs, and other devices you don't have to grab exist. What's available where you are etc is unfortunately variable. See if your doctor or the local PT has ideas too.
