I too have a short inseam compared to my overall height. And I used to have trouble with my hands hurting or getting numb. But that was 25 years ago when I was in my 30's. I have been very careful when buying a bikes since then. I don't rely on frame size or even stand-over height. I test ride it to make sure it's not too large. I find that I need a smaller bike than most people my height. That can make for less availability of used bikes in my size. But when I buy one it always fits. And life is too short to ride bikes that are uncomfortable.
