I have a Surly 1x1 bar on my commuter. It has a slight curve to it and it's amazing what a difference that has made, compared to the straight bars I have used on mountain bikes. My bike is a single speed, so I stand a lot on hills, and my wrists are comfortable both sitting and standing. There are lots of similar bars out there now. I'd suggest that you try to find a bike shop that will work with you, make some recommendations and maybe let you try out a bar or two that you think might improve your situation. If you wrapped the bar with black tape at the stem during your trial period, you could probably avoid marking it up in case you have to return it. Good luck.
