What are the causes of testicular distension and pain?

Testicular swelling and pain may be caused by various factors, including but not limited to the following conditions: 1. Testicular torsion: This is an emergency condition in which the testicular blood vessels twist, blocking blood flow and causing severe pain. Immediate medical attention is required. 2. Epididymitis or orchitis: Usually caused by bacterial infection, it may lead to swelling, redness, and pain, and may be accompanied by fever. 3. Varicocele: Enlargement of the veins around the testicle can cause pain and discomfort, particularly after prolonged standing. 4. Testicular tumor: Although uncommon, tumor growth may cause testicular enlargement and pain. 5. Physical activity or injury: Vigorous exercise or direct trauma may result in temporary pain. Please note that if testicular pain occurs, especially sudden and severe pain, prompt medical attention is essential.
