Whenever I pee, 80% of the urine comes out in one single time in 1 minute .But the rest 20% comes out in 2-3 minutes with few drops. And I still feel that some urine is left inside . This has been happening to me since 6 weeks. No burning sensation while urinating. I have the problem of 2nd stage haemorrhoids also and no other condition. My blood report is attached in which there is high potassium. What should be next course of action for it?
