What does the l5 nerve root control?
The two nerves most commonly pinched in the lower back are L5 (lumbar 5) and S1 (sacral 1). Pinched nerve at L5. The L5 nerve supplies the nerves to the muscles that raise the foot and big toe, and consequently, impingement of this nerve may lead to weakness in these muscles.
Thus the L5 is the largest and strongest lumbar vertebra, but is also the most susceptible to stress-related injuries. The L5 vertebra is located in the spinal column of the lumbar (lower back) region inferior to the L4 vertebra and superior to the sacrum.
- Passive treatments for low back pain from degenerative disc disease may include:
- Pain medication. Typical pain medications used to treat the low back pain include acetaminophen, NSAIDs, oral steroids, narcotic drugs, and muscle relaxants.
- Chiropractic manipulation.
- Epidural injections.
- TENS units.
- It can cause permanent spinal cord injury. Myelopathy occurs from spinal stenosis that causes pressure on the spinal cord. If untreated, this can lead to significant and permanent nerve damage including paralysis and death.
- Guide to nerve root compression. A compressed nerve is the impingement of a spinal nerve root by a condition in the spine. The symptoms that signal the possibility of a compressed nerve root, such as pain, tingling, numbness or muscle weakness, can become chronic and debilitating over time.
Weakness of any of these muscles can create a pathological gait. Compression of the L5 nerve will also cause numbness, paresthesias (pins and needles) and pain in the L5 distribution. This is buttocks pain that radiates down behind the thigh to the back of the calf and then to the top of the foot.
- If you have a herniated lumbar disc, you may feel pain that radiates from your low back area, down one or both legs, and sometimes into your feet (called sciatica). You may feel a pain like an electric shock that is severe whether you stand, walk, or sit.
- Thus the L5 is the largest and strongest lumbar vertebra, but is also the most susceptible to stress-related injuries. The L5 vertebra is located in the spinal column of the lumbar (lower back) region inferior to the L4 vertebra and superior to the sacrum.
- Injury or weakness can cause the inner portion of the disk to protrude through the outer ring. This is known as a slipped, herniated, or prolapsed disk. This causes pain and discomfort. If the slipped disk compresses one of your spinal nerves, you may also experience numbness and pain along the affected nerve.
