My kidney started hurting off and on a week ago. I would notice it mostly in mornings when I got out of bed (I would have to be gentle, as my kidney would hurt really bad and almost make it so that I couldn't move the left leg/lower body) and then again at night. It started with an off and on pain; however over the past couple of days, it doesn't seem to be going away.
Haven't changed my diet. Take Vyvanse for ADHD - never had this cause pains. Lack of sleep becuase of 3 month old.
