Pinched Lumbar Nerve
Pain by location
A pinched lumbar nerve, as the name implies, occurs in the lumbar (lower) region of the spine. Below is a guideline of the most common symptoms experienced with a pinched lumbar nerve.
- Pinched nerve at L5 – The L5 nerve controls the muscles that raise the foot and big toe, and, consequently, compression of this nerve may lead to the weakening of these muscles.
- Pinched nerve at S1 – Impingement of the S1 nerve can lead to weakness of the large gastrocnemius muscle in the back of the calf, causing difficulty with foot push off. Numbness from the S1 nerve presents itself on the outside of the foot. Pain will be located in the lower back, running to the buttock, down the back of the thigh and calf, to the lateral aspect of the foot (the little toe).

- Pinched nerves at L3, L4 and L5 – The sciatic nerveis the largest nerve in the body. It starts in the low back at lumbar segment 3 (L3). The sciatic nerve roots run through the bony canal, and at each level in the lower back, a pair of nerve roots exits from the spine. Each nerve root is named for the upper vertebral body that it runs between (for example, the nerve that exits at L4-L5 is named L4). The nerve passing to the next level runs over a weak spot in the disc space, which is the reason discs tend to herniate (extrude) right under the sciatic nerve root and can cause sciatica. The sciatica symptoms (low back pain, leg pain, numbness, tingling and weakness) vary depending on where the pressure occurs on the nerve. For example, a lumbar segment 5 (L5) nerve impingement can cause weakness in extension of the big toe and potentially in the ankle (a condition called foot drop).
Laser Spine Institute offers minimally invasive treatments to address the underlying cause of a pinched nerve. Our Discectomy, Foraminotomy or Laminotomy is performed to relieve the pinched nerve and allow blood and nutrients to flow to the affected area again. The spine surgeons at Laser Spine Institute have performed these and other procedures thousands of times.
