80 year old male broken humorous took okyconton as the hospital was releasing was given a catherata - however after terribly constipated and visiting nurse said OK to take magnesium sitrate; which took and within a short time, very violent, cannot stop, after the laxative slowed down it is difficult to urinate, it aches and now cannot urinate - I may feel like urinating but a slight bowl movement occurs - is this dangerous to wait until an appointment at 8:00 am or should a visit be set now?
