I have a weird pain around my right kidney area. seems like the more i do i get tired in that area . if i rest it goes away. what could this be?

Muscle fatigue: If pain is from kidney, it will hurt regardless of time of day. You maybe experiencing some muscle strain/fatigue of the paraspinal muscles (muscles next to spine), thus feeling aching/sore when overworked/used. Since resting resolves the pain, physical conditioning/back exercises will likely help that after several weeks. If persistent, consult doc. Good luck.
