###Human: What is the chance of herniated disc L5-S1 causing pain in groin area and testicle? ###Assistant: Hello. Well, the pain of L5-S1 disc herniation typically is pain on the backside of the thigh and radiates down to the leg on the outer aspect and to the foot. The nerves of the groin region are more below. But, as in your case, if the disc prolapse is big then it can also compress nerves of the groin region and can cause pain. Do you have any bladder issues or any numbness in your private parts?
