What nerve root may be impinged by a left foraminal or extraforaminal disc herniation at L3 L4

What nerve root may be impinged by a left foraminal or extraforaminal disc herniation at L3 L4?

Whereas a central, paracentral, or subarticular disc herniation may impinge the traversing nerve root at a given level, a foraminal or extraforaminal disc herniation may affect the exiting nerve root. At L3-4, the L3 nerve root exits, and therefore the left L3 nerve root may be impinged by a left foraminal or extraforaminal disc herniation at L3-4
