Haze gave a lot of good advice there. Not sure if it would help with anything but when I feel exhausted I usually like to sketch stuff while laying in bed with my arm sort of resting on the bed sometimes .... it's not very hand related but ... maybe it would help you with how you're holding the pen .. more specifically .. will help you loosen your grip a bit. It kinda does it for me.
