Hi, when i pee i feel something is blocking it and it hurts a bit because of that blockage, there is no blood or whatsoever. what should i do?

See your doctor: You should see your doctor and have a urine analysis to check for infection. Is there any chance the blockage may represent a foreign body?

Stricture to check: If you feel that there is an obstruction when you urinate, you may be right. A visit to your urologist will can provide you with a diagnosis. The signs of stricture are, poor flow, dribbling after urination and sense of incomplete bladder emptying.
