Hi and thank you so much for trusting us with your health query. Testicular torsion is twisting of the cord containing blood vessels and nerves supplying the testes. This is most common in young men. The main symptoms are sudden severe pain that seems not relieved by any physical measure. Generally happens without trauma. It is an emergency and need to be addressed within six hours if the testes must be salvaged. I hope you find this helpful. Thank you so much for using our services and please feel free to for more information or clarifications if need be. I wish you the best of health. Dr. Ditah, MD.
