Does L4 L5 cause sciatica?

Most sciatica is caused by problems that affect the L4, L5, or S1 nerve roots. The nerve may be compressed or irritated, usually because it's being rubbed by a disc, bone, joint, or ligament. The resulting inflammation makes the tissues and the nerves more sensitive and the pain feel worse.
