I am 45, male on lipitor for about 2 months now. I am experiencing kidney pains that wake me up at night. I have been noticing dark urination prior to the kidney pain coincidently. After doing a quick search for information on it I find that the statin medication Lipitor is the culprit - OBVIOUSLY. Not waiting for advice from a doctor to tell me what to do about it. Bye Bye Lipitor and hello more excercise with an increase in fresh friuts and vegetables in my diet. Good luck to all taking this drug.
