How do you know if your stem is the right length? Like at what point is it better to lower your bars and get a shorter stem vs just raising your current and how should a right fit feel?

Some more personal things about my current fit is sometimes I feel ever so slightly stretched out, a bit of pain on the heel of my hands, and right where my hamstring meets my butt. Mostly just looking for a little insight on picking a stem length I just added the second part in case anyone has any thoughts on that. I understand you really can't do a bike fit over text on the internet.

Thanks!
