I’d recommend raising your handlebars until there’s as much pressure on the bars as you’d experience with your hands on your car steering wheel.
Normally you could do this by fitting one of those ‘delta’ brand steerer tube extenders, the kind that clamp to your steerer and add an extra two inches of handlebar height.
However as you’re on a Specialized with a carbon fork there’s no way you could add one of these without ruining your warranty or potentially the fork itself. They’re pretty sniffy about what you can do to the front end of the bike.
So, it’s new fork time (maybe you can find a nice cro -mo one), leave it uncut, add the delta stem raiser, add spacers to suit and possibly an angle-adjustable stem until there’s no pressure on your arms/ wrists.
It’s not a lot of work and it sure beats nerve damage.
