Where Is The Sciatic Nerve In The Knee

Spinal Disc Herniation & Sciatica : How to Cure Extreme Pain & Weakness in the Leg From Sciatica

The sciatic nerve is located between the pelvis and the foot. This nerve is also the largest nerve in the body. Sciatica of the knee occurs when the nerve becomes damaged and causes pain in the knee area. There are two types of sciatica of the knee: acute and chronic .

You only have one nerve that passes through your knee that is at risk of compression. Its the peroneal nerve, a branch of the sciatic nerve.

As the knee moves back and forth, the peroneal nerve travels along with these muscles. Occasionally, a peroneal nerve can be compressed or stuck alongside any of these muscles. When these muscles are stuck, it can cause inflammation or injury and, consequently, pain outside the knee.

How Does The Sciatic Nerve Affect The Knee

As you grow older , the vertebrae discs protecting your spine may degenerate or bulge out, pressing on the nerves and irritating them. The sciatic nerve roots located in your lower back transmit pain sensations depending on which disc is protruding.

If the pinched nerve is at the second, third, or fourth lumbar vertebrae, referred pain will be received by the knee. Referred pain is a phenomenon where discomfort is felt at a location other than where the cause is situated as a result of pain signals being sent along interconnected sensory nerves.

Causes Of Piriformis Syndrome

Your anatomy may be behind your piriformis syndrome. This is known as primary piriformis syndrome and occurs when you have a split piriformis muscle, split sciatic nerve, and/or an atypical sciatic nerve path.

Secondary piriformis syndrome is far more common and is caused inflammation of soft tissues, muscle spasm or both, resulting in nerve compression. Direct trauma to the buttock can lead to inflammation, scarring and contractures of the piriformis muscle

This might be the result of a major event like a car accident or a fall. However, the most common cause is likely the gradual tightening of the piriformis muscle due to poor muscle fitness. Activities, such as long distance running or prolonged standing without proper stretching and strengthening of piriformis muscle is a common scenario in patients with piriformis syndrome .

What Are The Causes

Sciatica can be caused by a number of conditions that irritate or compress the sciatic nerve:

  • Piriformis syndrome: Tightening or spasm of the piriformis muscle can compress the nerve.
  • Trauma: A sports injury or fall can fracture the spine or tear a muscle and damage nerves.
  • Herniated disc: The gel-like center of a spinal disc can bulge or rupture through a weak area in the disc wall and compress nerves.
  • Stenosis: Narrowing of the bony canals in the spine can compress the spinal cord and nerves.
  • Osteoarthritis: As discs naturally age they dry out and shrink. Small tears in the disc wall can be painful. Bone spurs can form. The facet joints enlarge and ligaments thicken.
  • Spondylolisthesis: A weakness or stress fracture in the facet joints can allow a vertebra to slip out of position and pinch the nerves.

Leg pain can also be caused by a joint problem in the hip or sacroiliac joint. This type of referred pain is quite common, but is not sciatica.

Standard Treatment Options For Sciatica

Pin on Back pain

A quick internet search or visit to your doctor might yield any combination of the following recommendations to treat sciatica:

  • Rest
  • Ice
  • Steroid injections

While these treatment approaches might be good to accomplish short-term relief, if the root cause of your sciatica flare up goes uncorrected, chances are it will recur eventually.

Do You Have A Pinched Sciatic Nerve

The sciatic nerve is the largest nerve in the body. You have two sciatic nerves. Each one runs from the lower spine down through the buttock, the back of the thigh, and down to the foot. Sciatica is a condition that occurs when the sciatic nerve is compressed. This results in pain in the hip, back, and the outer leg. Some people experience cramps and shooting pain that may interfere with the ability to sit or stand. A slipped disc, a herniated disc, spinal stenosis, or a slipped vertebra may may cause sciatica. The condition may be treated with pain meds, exercise, physical therapy, stretching, massage, and ice packs. Severe cases may be treated with steroid injections or surgery.

Spinal stenosis may occur when the spine is injured and tissue swelling puts pressure on the nerve roots or spinal cord. An injury to the spine may cause a bulging disc, or herniated disc. This can protrude into the spinal canal. When a herniated disc puts pressure on a nerve root, this is known as a pinched nerve. This results in numbness, tingling, and pain in areas where the nerves travel. Some cases of disc herniation are treated surgically.

Bulging Or Herniated Disc

A lumbar bulging or herniated disc is the most common cause of sciatic nerve pain. Research suggests that herniated discs are responsible for 90% of sciatica cases.

Intervertebral discs sit between vertebrae in the spine, providing support, cushioning and shock absorption. Each disc contains a soft, jelly-like nucleus surrounded by a tough outer shell. Age and natural wear and tear over time cause spinal discs to dry out, weaken and develop tiny tears. The supporting ligaments start to weaken as well, causing the disc to slip and bulge out of place. Eventually, pressure and degenerative changes can lead to the jelly-like nucleus leaking out of a tear in the outer shell a condition called a herniated disc. A herniated disc can also occur suddenly from a traumatic accident like a fall, car crash or sports accident.

A disc thats bulging out of place can irritate, rub against or place pressure on nearby structures including the sciatic nerve. Similarly, pieces of a herniated disc can press against or compress the sciatic nerve root. And the jelly-like disc nucleus contains a chemical irritant that causes nerve inflammation when released into the spinal space.

Are Varicose Veins Painful

Veins are blood vessels that deliver blood back to the heart. Veins have valves that assist the one way flow of blood. When these valves weaken or become damaged, blood may pool in the veins and cause them to stretch. Bulging, swollen, purple, twisted varicose veins result. Varicose veins may cause leg pain, throbbing, cramping, burning, and heaviness. Risk factors for varicose veins include being overweight, sitting or standing for long periods of time, and exercising. Wearing compression stockings can give your legs extra support and decrease the risk of varicose veins. Rarely, varicose veins may be associated with blood clots or skin ulcers. Treatments are available to get rid of varicose veins.

Do You Have Burning Pain In Your Thighs

Meralgia paresthetica is a condition in which a nerve in the thigh becomes compressed. This leads to painful burning, tingling, and numbness in the upper thigh. Risk factors for the condition include wearing tight clothes, being overweight or pregnant, or having scar tissue due to surgery in the groin region. Over-the-counter pain relievers like ibuprofen and acetaminophen may provide relief of symptoms. If the pain is severe or lasts for more than a couple of months, see your doctor who can prescribe stronger medication.

How Is Sciatica Related To Leg Swelling

Sciatica  The Cause Of Your Back And Leg Pain?
  • Sciatica surgery can sometimes be avoided with conservative home care
  • Although there can be a correlation between sciatica and leg swelling, the cause is not always clear. Sciatica is a general term describing symptoms caused by compression of the sciatic nerve which starts in the lower back and runs all the way down the leg. In addition to pain in the lower back, compression of this nerve also causes radiating symptoms like tingling, numbness and muscle weakness in the hips, buttocks and legs.

    Leg swelling is more commonly associated with fluid retention and circulatory issues, not nerve compression, so it is not typically listed as a sciatica symptom. However, sciatica and leg swelling can be connected because the pain and limited mobility from sciatica often lead to an inactive lifestyle that can cause fluid buildup and blood flow problems. If you have been living with sciatica and are also dealing with swelling in your legs, it is important to see your doctor for a clear diagnosis of what is causing both conditions.

    What Is The Sciatic Nerve

    The sciatic nerve originates near the base of the spine, where nerve roots at the L4, L5, S1, S2, and S3 vertebrae exit the bony opening of the spine and join into a single, large nerve and exits a bony arch called the sciatic notch. The sciatic nerve travels through the pelvis, passing under the front surface of the piriformis muscle as it travels through the pelvis.

    It then cuts into two branches before going down each leg, branching out at the back of the knee to divide into the tibial and peroneal nerves, both of which supply the lower leg and foot. The sural nerves branch off from the tibial and peroneal nerves, terminating in the foot.

    The sciatic nerve is responsible for bending the knee, bringing the thighs together , and flexing and extending the ankles and toes. It also provides sensation to the back of the thigh, the entire lower leg, the ankle, and the sole of the foot.

    Visualizing the piriformis muscle and the sciatic nerve

    The piriformis muscle originates at the front of the sacrum near the sacroiliac joint capsule and attaches to a bony knob on the femur at the outermost part of the hip.

    The piriformis helps externally rotate and abduct the hip, fancy words for turning your hip outward and bringing your thigh outward to one side while your hip is bent, such as when raising your knee and bringing your leg out when getting out of a car seat. It also offers stability while walking, running and standing.

    Can Knee Pain Radiate Up Leg

    When you have sciatica, you may experience the following knee symptoms:

    In the front, sides, or back of the knee, a hot sensation, sharp pain, or dull ache may be felt. A person may also experience Having difficulty bearing weight on ones knee.

    Knee weakness, especially when trying to straighten the leg, is also a common symptom of sciatica.

    If you suffer from sciatica, you may also suffer from knee pain, buttock, thigh, calf muscles, and foot pain. Most frequently, sciatica pain will only affect one leg at a time, so pain in both knees is rare in this case.

    Can A Herniated Disc Cause Abdominal Pain

    Yes, it can, but it is not common. Lateral disc herniation is a type of herniated disc that can lead to abdominal pain. A thoracic herniated disc that herniates lateral, or on one side, is more likely to press against the nerve root that exits at that level of the spine and cause radiating chest wall pain or abdominal pain.

    It is common for a thoracic disc herniation to be asymptomatic or for patients to complain of nonspecific symptoms, like chest wall pain, abdominal pain and upper extremity pain. In some cases, pain in the lower extremity or groin is also experienced.

    Symptomatic thoracic discogenic pain syndrome is a rare occurrence that can be difficult to diagnose.

    What Causes Sciatica Pain

    Lumbar Herniated Disc

    A lumbar herniated disc occurs when the rubbery disc between the vertebrae of the lower back bulges or ruptures, causing irritation and compression of the spinal nerve roots. The most common cause of sciatica is a bulging disc or herniated discs.

    Degenerative Disc Disease

    A vertebral disc may begin to wear out with age as a result of degenerative disc disease. A thin disc causes the space between each vertebra to compress, causing the sciatic nerve root to be compressed.

    A disc with a worn outer covering may leak fluid out onto the sciatic nerve and irritate it.

    Bone Spurs

    Overgrowth of bone on vertebrae can cause sciatic pain. The bone spurs usually form near vertebrae affected by osteoarthritis.

    Spinal Stenosis Spinal Discs

    A narrowing of the spinal canal and the sciatic nerve roots is caused by spinal stenosis. Arthritis and aging can contribute to the narrowing of the arteries.


    Anatomically, vertebrae are stacked one onto the other to provide stability. Spondylolisthesis occurs when one vertebra slips forward over the one below it and presses into the sciatic nerve.

    Piriformis syndrome

    Piriformis syndrome refers to irritation of the sciatic nerve caused by too tight piriformis muscles and muscle weakness. If you sit for a long time, walk upstairs, run, or walk for a long time, the symptoms may worsen. The piriformis muscle extends from the top of the thigh bone to the sacrum .
