L5-S1 helps transfer loads from the spine into the pelvis and legs. Lumbar Spine Anatomy Video Save. The L5-S1 segment bears all the weight of the upper body and offers the most flexibility in movement, making this spinal motion segment prone to injury.
What are the symptoms of L5-S1 nerve damage?
A herniated disc at lumbar segment 5 and sacral segment 1 (L5-S1) usually causes S1 nerve impingement. In addition to sciatica, this type of herniated disc can lead to weakness when standing on the toes. Numbness and pain can radiate down into the sole of the foot and the outside of the foot.

However, patients with severe neck, upper back, and mid-back issues that compress the spinal cord may also experience pain and weakness in their legs.
What causes L5-S1 radiculopathy?
The most common cause of radiculopathy is a herniated lumbar disc. When disc material protrudes from the disc space into the spinal canal, it can compress a nerve root. Radiculopathy can be caused by an accident, injury or lifting a large amount of weight improperly.
What are the symptoms of S1 nerve root compression?
S1 radiculopathy typically results in numbness down the back of the leg into the outside or bottom of the foot. Weakness is another symptom of nerve root compression. However, it is less common than pain and numbness. This displays as decreased function in the muscles supplied by the nerve root that is compressed.
How do you fix L5 S1 pain?
Treatment of L5-S1 usually begins with: Medication. Over-the-counter (OTC) medications, such as non-steroidal anti-inflammatory drugs (NSAIDs) are usually tried first for pain stemming from L5-S1.
