I've found that riding drop bars with some outward flare puts my wrists in a more ergonomic position and help with the pain. If you plop your arms on a desk or table in front of you, note that your hands want to bend in a bit. Looking at it from a C&V standpoint, Nitto B135 bars have a little flare. From a non-C&V standpoint, look at the host of gravel bars available that have varying amounts of flare. I no longer have any bikes that have zero-flare drop bars.
