Where do L3-L4 nerves go?
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.

Can a pinched nerve be detected with an MRI?
MRI scans which show soft tissues, such as nerves and discs, are generally preferred over CT scans which show bony elements. Advanced imaging can show exactly which nerve or nerves are being pinched and what is causing the nerve to be pinched.
