I have noticed this several times: whenever I take creatine (2 g), my lower back becomes very stiff. The stiffness extends from my buttocks to my lower back, and I have difficulty bending forward. This happens even when I have not done any weight lifting or strenuous exercise. Could creatine be triggering this stiffness? ESR,
