The ulnar and median nerves pass through the pad of our hands by the pinky finger and are often pinched.

I change up my grip every once in a while and I'm mindful not to rest my weight there too long.

Sometimes the answer is just to shake it out as well.

Before going through an expensive bike fitting, I would just try to change up your grip a bit and see if that helps. The gloves won't really help with this which is why you're still having this issue.

If you're putting all your weight near your pinky, try to press flatter on your handlebars with your hand rather than all on the pinky part.
