I've had the same problem in the past. I got the Iso grips w/ boss and that helps BIG TIME! On long runs where the throttle stays in one place, I'll sometimes tighten up the friction lock and give my hand a break. In the summer months I wear weight lifting gloves due to the extra padding.
Relaxing is very important, and that doesn't always mean your grip. I've had similar problems with fingers, but the cause was tightening my neck and back tension. Nerves are wacky and run all over. I'm no Doc but I know this from experience.
And to answer your question, yes different grips can make a difference. Forget looks and go with what feels good. The big padded ones work for some, but they get funky if you ride in the rain and they rot, plus they're like holding on to beer cans if you wear gloves. The slick, pretty, skinney ones look real uncomfortable to me, but my g/f always wears gloves and likes hers except on road trips. She uses a palm paddle and throttle lock a lot on the road.
I grew up on Triumphs which all had the sublime shape, hard grips. Year before last I put on the nostalgic genuine HD grips that are the same shape and I've had NO finger, forearm or back problems while riding since. But everybody's different....
Could be an entrapped nerve issue at the elbow. That nerve controls the ring and pinkie. Carpal nerve in wrist controls thumb,middle and first finger. I have both issues and have had good success with the throttle rocker. I use them on both grips. Only $10. The Crampbuster is similar. One good thing about the Crampbuster is that it can be adjusted on the fly whereas with the throttle rocker you have to stop the bike.
