In 2019 i started riding semi-seriously. Do a few hundred miles then a metric century. It took me about 4 days for my hands to stop being numb after that ride. All through the winter 2019-2020 I had hand pain when i rode. Tried everything from gloves to seat position to stem height and length. Took pain meds and used squish balls in ride (on a trainer).

Did all this no relief. Then suddenly it all stopped. I think it was mainly due to in increase in core strength but I also got my seat angle correct, used multiple hand positions and in general finally got the bike adjusted to fit me. Of course that is just me.
