It is advisable to go to the hospital for relevant examinations to clarify the cause of the pain. 1. Urethral infection can cause pain in the urethra and is accompanied by symptoms such as urinary frequency, urinary urgency and painful urination. The urethroscopic examination shows that the mucosa of the urethra is congested and edematous with local erosion, which will certainly produce painful symptoms. 2. The presence of stones or tumors in the urethra causes mucosal rupture or damage, and the stones are embedded in the urethra, stimulating the mucosa and causing continuous stinging pain. The tumor grows with the volume and causes local damage to the urethra, which can cause continuous pain, and most of them have abnormalities in urination, such as symptoms of urinary obstruction or poor urination, and in serious cases, they may even cause inability to urinate, which needs to be further identified by urethroscopy. 3. If there has been trauma to the urethra, such as riding injuries or blows, which can cause local mucosal contusions and cause pain, the patient mostly has a clear history of trauma.
