Testicular torsion is a medical emergency that occurs when the spermatic cord twists, cutting off blood flow to the testicle. It causes sudden, severe testicular pain, often accompanied by swelling, nausea, and abdominal discomfort. Without treatment within 6 hours, the testicle may be permanently damaged.
Because symptoms can overlap with other conditions like epididymitis or a hernia, identifying the cause quickly matters. Take a free, instant, online symptom check to better understand your symptoms and decide on the right next steps.
