Before springing for a costly and fragile fork, try getting the bars higher, or closer to you. That will reduce pressure on your hands, at the expense of a less aerodynamic riding position. Presumably, if you're touring, you want to be comfortable and spend some time looking around. It's just my opinion, but after many, many years of hard-won experience, I'd urge you to set your bars no lower than the height of your saddle.
