Recently, i feel discomfort everytime i pee, but i ignore it.. one day, when i peeing it have a blood at the end of my pee.and i feel hurt.

May have a stone: See a urologist. If I can't get to one see a general Practioner. U may have an infection too, but sounds like a stone. Hydrate well with water!

Call urology.: Ian, any person with blood in their urine must be evaluated by a urologist. Infection, cancer, kidney stones, anticoagulation, a medical kidney disease, or a bleeding disorder can cause blood in the urine. Often the cause of bleeding can be found, and less often, we do not have a cause. See a urologist, who can investigate the problem and provide a course of action. Best of luck, Ian.
