What causes a burning or stabbing pain in the urethra?

A burning or stabbing pain in the urethra may be caused by various factors. In men, common causes include urethritis and balanitis. Urethritis is an infection of the urethra caused by various pathogens, which may present with symptoms such as urethral itching, painful urination, redness, swelling, and increased discharge. Balanitis refers to inflammation of the mucosa of the glans penis, which can lead to redness, swelling, pain in the glans, and urethral symptoms. In women, common causes are urinary tract infections (UTIs) and vaginitis. UTIs typically manifest as a burning sensation, pain during urination, urgency, and frequent urination. Vaginitis may affect the urethra due to the close proximity between the vagina and urethra, leading to urethral discomfort. Additionally, sexually transmitted infections, urethral stones, urethral tumors, or polyps may also cause burning or sharp pain in the urethra. If such symptoms occur, it is recommended to seek medical attention promptly for accurate diagnosis and appropriate treatment.
