Fingers going numb especially last 2 on my hand.

[Flowrider]

I'm confused...

For some reason, the last two fingers on my right hand started getting numb.

I've changed my grips, put in a handlebar riser, and after a while, twisted the bar back and forwards, moved my brake and gear levers to different positions, and changed my gloves, but still, during a long ride, the last 2 fingers go numb. All the above-attempted solutions were given a long trial period, ie 60 or so ks, but no result

They don't stay numb too long.

Has this happened to anyone?

If so, do you know why and what was your remedy?

Any advice will be gratefully appreciated
