<unk>  is define as  pain or burning, stinging, or itching of the urethra or urethral meatus during or just after urination.Dysuria happens due to bladder muscle contraction and peristalsis of the urethra, which  cause the urine to come in contact with the inflamed mucosal lining, which in turn stimulates pain receptors and causes one to feel pain or burning.
