my father is almost 60 years old, he has high blood pressure and is on medication for it. just saturday we all went up to the cottage, sunday my father, my husband, and my brother inlaw carried a boat into the water, there was no moter, just padels. my father did most of the paddeling. sunday afternoon he noticed blood in his urine, and about 3am monday morning he also had some pain in his kidneys, and noticed blood coming from his retom almost like he was on a period. i begged him to see a doctor, but he refuses to go. says he might go next week. monday morning about 7am my father said it looked like the blood had stoped. i am concerned. we my husband and i had to come back home for work. what do you think this bleeding could be from? he also said he had no straining at the bowel, he was just bleeding.
