Have a week urinary stream sometimes, usually middle of night. i have urinated frequently all my life. on a muscle relaxer but noticed here and there before, but believe i was on prednisone when it happened before. hope its not prostate related?

Doctor can evaluate: It is not normal to "urinate frequently all my life." It's also not normal to have a weak urine stream. One's doctor can evaluate to see if there is a blockage. It would be more reassuring if such a patient had gotten ultrasound and x-ray studies when younger (as in childhood), to make sure he was not born with a partial blockage in his urinary system.
