Like 1 said, it’s usually the wrong height (or a bad grip) or you’re putting too much weight on it. Canes shouldn’t be used for major weight bearing, especially long term. It should be used for stability and balance, and MINOR temporary weight bearing. If you need to put your weight onto it, you need to talk to your doctor/physical therapist about weight bearing mobility aids like crutches or walkers.
A good rule to follow is about 15% of your body weight (think like ouch I stubbed my toe and wanna get a little off it for a minute but can still put most of my weight onto it type of offloading) and absolutely no more than 25% of your body weight. And for transient/inconsistent pains like arthritis (big one for me) that comes and goes in severity
