Where does L1 and L2 cause pain?
L1-L2 Herniation: The L1 spinal nerve root is responsible for the psoas muscle, which is found within the body cavity along the lumbar spine. Weakness in the psoas muscle and pain in the groin and front of the thigh may occur; the former can cause difficulty with lifting the leg, for example, while walking up stairs.
What does the L1 nerve control?
L1 spinal nerve provides sensation to the groin and genital regions and may contribute to the movement of the hip muscles. L2, L3, and L4 spinal nerves provide sensation to the front part of the thigh and inner side of the lower leg. These nerves also control movements of the hip and knee muscles.
What is lumbar L1?
The L1 vertebra is the topmost section of the lumbar spinal column. This section of the spine contains a portion of the spinal cord. Injuries to the L1 spine can affect hip flexion, cause paraplegia, loss of bowel/bladder control, and/or numbness in the legs.

lumbar
The L1 vertebra is located in the spinal column of the lumbar (lower back) region inferior to the T12 vertebra and superior to the L2 vertebra. Like the other lumbar vertebrae, L1 has a large, roughly cylindrical region of bone known as the body, or centrum, which makes up most of its mass.
