L2 is the lowest vertebral segment that contains spinal cord tissue
. After that point, nerve roots exit each of the remaining lumbar levels beyond the spinal cord. Injuries below this level (at the L3, L4, and L5 vertebrae) affect the hips and legs and may cause numbness extending to the feet (sciatica).

Accordingly, what does L2 nerve control?
Functions of the Lumbar Spinal Nerves L2, L3, and L4 spinal nerves provide sensation to the front part of the thigh and inner side of the lower leg. These nerves also control movements of the hip and knee muscles.
Despite everything, where does L2 cause pain? L2-L3 Herniation: The L2 nerve root is responsible for the iliopsoas muscles. A disc herniation at this level may cause weakness in an iliopsoas muscle, which may cause difficulty while walking up the stairs and/or pain that radiates into the front of the thigh.
Just, where is lumbar 1 and 2 located?
The L1 vertebra is located in the spinal column of the lumbar (lower back) region inferior to the T12 vertebra and superior to the L2 vertebra. Like the other lumbar vertebrae, L1 has a large, roughly cylindrical region of bone known as the body, or centrum, which makes up most of its mass.
What are the symptoms of L2 nerve root compression?
For example, if you have a bulging disc between the 2nd and 3rd lumbar vertebra (L2-L3), and it pinches the L2 nerve root, you may experience back pain with aching, burning or shooting pain, numbness and tingling in the thigh, sometimes going down into the lower leg or foot.

A limited description of the specific lumbar spinal nerves includes: L1 innervates the abdominal internal obliques via the ilioinguinal nerve; L2-4 innervates iliopsoas, a hip flexor, and other muscles via the femoral nerve; L2-4 innervates adductor longus, a hip adductor, and other muscles via the obturator nerve; L5 ...
S1 NERVE ROOT DAMAGE: This pain can come in the form of numbness, tingling, weakness and shooting. S1 nerve root Radiculopathy may cause pain or numbness in the little toe and top of the foot. Consequently, patients find it difficult to stand on their tip-toes or raise their heel off the ground.
If you have a fracture below the L1-L2 (first and second vertebrae in the lumbar spine), you won't have a spinal cord injury, but it's still possible to injure the nerves. Your back also has muscles, ligaments, tendons, and blood vessels. Muscles are strands of tissues that power your movement.
The L2 spinal nerves affect the muscles that allow you to bend the hips (hip flexors) and sensation at the upper thighs (will present similarly to an L1 injury). The L3 spinal nerves affect the ability to straighten the knees (knee extension) and sensation at the lower thighs and knees.
This "exiting" nerve root is found within the neural foramen. For example at the L2-L3 level, the exiting nerve root found in the neural foramen is L2 (see image below). The nerve root that is waiting to exit at the level below is referred to as the traversing nerve root and can be found within the lateral recess.
A muscle or ligament strain is one of the most common causes of lower back pain. It can be caused by: repeated heavy lifting. bending or twisting awkwardly.
An activity that exerts tremendous pressure on your lower spinal discs is sitting. If you have a herniated or bulging disc, this increase in pressure within your disc may cause the bulge to become more pronounced, which may aggravate your lower back pain when you sit.
Treating Nerve Root PainTaking non-steroidal anti-inflammatory drugs (NSAIDs)Interventional techniques such as nerve blocks (spinal injections)Epidural injections in the lumbar and cervical spine.Nerve killing procedures such as radiofrequency ablation.Engaging in exercise and physical therapy.Activity modification.
Most of the time, symptoms from a pinched nerve will start to feel better within 6 to 12 weeks of nonsurgical treatment.
The weakest part of the spine is the cervical spine, which is made up of seven vertebrae.
Pinched nerve signs and symptoms include:
- Numbness or decreased sensation in the area supplied by the nerve.
- Sharp, aching or burning pain, which may radiate outward.
- Tingling, pins and needles sensations (paresthesia)
- Muscle weakness in the affected area.
- Frequent feeling that a foot or hand has "fallen asleep"
Pelvic parasympathetic nerves: arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra. Lumbar sympathetic nerves: inhibit the bladder body and excite the bladder base and urethra. Pudendal nerves: excite the external urethral sphincter.
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. For more severe pain, prescription medication, such as opioids, tramadol, and/or corticosteroids may be used.
The S1 nerve root also supplies innervation for the ankle jerk (tap on the achilles tendon and the foot goes down), and a loss of this reflex indicates S1 impingement, although it does not create loss of function.
An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.
Nerve Pain It's best to use cold when the pain is still sharp and move on to heat once that sharpness has subsided. The heat will increase blood flow and help tissues heal faster.
