I have a problem with my right hand, but it's not the type that lingers for days. I've tried the Specialized gloves, supposedly designed for the problem. It was worst. Over the years I've evolved away from any padding at all.
I use Fox gloves for both road and off road which have no padding and fit perfectly. It's not as bad with zero padding, but it hasn't totally gone away.
I use very soft grips on my mountain bike and soft, plush tape on the road bike. There is a molded pad designed to go under the tape for drop bars. I may try those. Padding the bars works better for me than padding the gloves.
