Sciatic nerve knee pain

Sciatic nerve knee pain: Causes, Symptoms & Treatment

Sciatica is a term for leg discomfort, achiness, numbness, or tingling. It is brought on by pressure or damage to the sciatic nerve. Sciatica is a sign of a health issue. On its own, it is not a medical issue.

What exactly is knee sciatica?

The sciatic nerve exits the pelvis at the back and travels to the feet. Sciatica of the knee is the term for pain emanating from a damaged nerve that radiates to the area around the knee. Knee sciatica may be acute (lasting less than six weeks) or persistent (more than six weeks). The best way to treat knee sciatica is with physiotherapy.

Neuropathy – sciatic nerve; Sciatic nerve dysfunction; Low back pain – sciatica; LBP – sciatica; Lumbar radiculopathy – sciatica

Major Sciatic nerve knee pain Causes for

When the sciatic nerve is under pressure or suffers injury, sciatica results. Beginning in the lower back, this nerve travels down the back of each leg. The lower leg and knee back muscles are under this nerve’s control. Additionally, it gives feeling to the sole of the foot, the back of the thigh, and the front and back of the lower leg.

The most common causes of Sciatica brought on by:

  • Slipped disc herniated
  • Vertebral stenosis
  • Parietal syndrome (a pain disorder involving the narrow muscle in the buttocks)
  • Pelvic fracture or damage
  • Tumors

Sciatica is more common in men between the ages of 30 and 50.

How can knee sciatica develop

Sciatica in the knee can have a variety of causes. The most frequent cause of sciatica in the knee is a prolapsed disc. The spinal disc’s constituent material may leak out and irritate the sciatic nerve, resulting in discomfort that may radiate as far as the knee. The following are additional causes of knee sciatica:

  • Vertebral stenosis
  • An injury to the spine
  • Malignancy
  • Infection
  • Bone conditions

How are the back and knee related?

Our backs and knees are connected by nerves, and our backs are where the nerves that control the knee muscles originate. Sometimes the discs between the vertebrae can protrude and push on these nerves as a result of injury or aging.

Depending on which disc is bulging, when a nerve becomes irritated, it will induce discomfort in a certain place of the body. The second, third, and fourth lumbar vertebrae in the lower back are home to the nerves that carry fibers to the knee. Referred pain, which is frequently felt in the knee, is frequently caused by irritation or injury to one of the nerves in this region.

Signs Your Knee Pain Is Related to Your Back

1- Do you feel backache and knee discomfort together

Consider whether you are feeling pain in other parts of your body if you have knee discomfort, whether it is a recurring issue or an isolated incident. Even if the two don’t seem to be connected, it’s important to note the discomfort and talk to your spinal specialist about it.

It’s worth looking into if you work a desk job or spend a lot of time in your car or on airplanes because back pain-producing knee pain is more common in those who sit a lot. Keep in mind that the back pain might not appear as bad as the knee discomfort; it might even merely feel tight muscles.

2- Are you getting bunions?

Although it may seem unusual, bunions can be an indication of underlying spinal problems. The big toe tends to slant at an abnormal angle, which creates space for “bone spurs” (also known as bunions) to develop. A weakening of the muscles frequently results in this toe angle. Our backs are connected to the inside and outside of our feet by nerves. The muscles in our feet can function differently and become looser as we become annoyed. The toe joint tilts as a result of this.

3- Your hamstrings are feeling tight?

If you frequently stretch your hamstrings to try to relieve discomfort or tightness and find that it is ineffective, there may be a back-related nerve problem at play. The biceps femoris is powered by the L5 nerve, which exits the lumbar spine by the outside hamstring muscle. If we have chronic hamstring tightness, problems with this nerve might also change how we move, which can have an impact on the knee.

4- Your hips or quadriceps are weak.

If you notice that your hip is deteriorating, it could indicate problems with your spine. When spinal issues make your hip muscles weaker, your knees can have to work harder to make up for the loss of strength, resulting in pain.

5- Sciatica Treatment Without Surgery

Physical therapy, medicines, therapeutic injections, and complementary therapies are frequently used as the first treatments for sciatica.

With nonsurgical treatment for 4 to 6 weeks, acute sciatica typically improves. Depending on the underlying cause, therapy times for persistent sciatica that lasts longer than 8 weeks may be longer.

6- Physical Therapy for sciatica

Physical therapy is an essential part of practically every sciatica treatment plan and combines stretching, strengthening, and aerobic conditioning. A physical therapy program may also include therapeutic exercises.

The following are the objectives of physical therapy and exercises for sciatica:

  • Boost the spine’s stability and the muscles in your hips, buttocks, and lower back.
  • Boost your core strength
  • Stretch tense, rigid muscles, such as the hamstrings
  • Encourage the body’s fluid and nutrition exchange by engaging in brief aerobic activities like walking, swimming, or pool therapy.


Over time, mild sciatica typically goes away. If self-care techniques don’t help symptoms, contact your primary care physician. Call if the pain is severe, lasts longer than a week, or worsens. Get prompt medical attention for:

  • Numbness or muscle weakness in a leg, as well as sudden, intense pain in the low back or leg
  • Pain following a violent injury, such as one sustained in a car accident
  • inability to control one’s bowels or bladder

Frequently asked questions ( SCIATIC NERVE KNEE PAIN SYMPTOMS )

What should I avoid if I have knee sciatica?

You ought to stay away from any activities that make your symptoms worse. Avoid ignoring knee sciatica symptoms as doing so could worsen your illness and prolong your recovery.

Are there any long-term consequences of knee sciatica?

Although it is extremely uncommon, people with chronic sciatica may be advised to have surgery. A suitable graduate physiotherapy program can treat most cases with sciatica of the knee, albeit the length of the program will depend on how severe the sciatica is.

How does sciatica pain feel?

Most people who experience sciatica pain describe it as a persistent burning sensation or a shooting pain that starts in the lower back or buttock and travels down the front or back of the thigh, leg, and/or feet. Numbness. The back of the leg numbness may accompany sciatica pain.
