Sciatica

Cairns Chiropractic would like to illustrate the structures involved with sciatica syndrome.

The Sciatic nerve (L4,L5,S1,S2) descends between the ischial tuberosity and the greater trochanter of the femur.

Symptoms may include weak hamstrings, leg and foot muscles. Sensory loss may also occur in the thigh, leg, and foot. Pain is associated in the thigh, leg, and foot.

 

Sciatica refers to a lower back pain that radiates down the leg. The pain can radiate down the front, back, or outside of the leg. The pain usually occurs after heavy lifting. However, it can also be gradual in onset. The pain is sometimes described as shooting. Symptoms are usually only experienced on one side. However, some causes can cause pain on both the left and right sides. Sometimes, lower back pain may be present. There may be weakness or numbness in different parts of the affected foot and leg.

A spinal disc herniation pressing onto one of the sacral or lumbar nerve roots can cause about 90% of sciatica. Other possible causes of sciatica include spinal stenosis and piriformis syndrome. A straight-leg-raising test can often help in diagnosing sciatica. If the pain below the knee is felt when the person lies on their back and raises their leg, the test is positive. Medical imaging is usually not necessary. Medical imaging is unnecessary if there are concerns about tumors or infections. Similar conditions may be present in diseases of the hip or infections such as early-onset shingles (prior rash formation).

Pain medication is often used as the first treatment. Evidence for muscle relaxants and pain medication is not available. People should continue to do their normal activities as best they can. Symptoms often resolve within six weeks. In fact, 90% of patients experience relief in under six weeks. Surgery may be an option if the pain lasts more than six weeks or is severe. Surgery can often speed up pain relief. Although it can provide some relief, the long-term effects are not known. If complications arise, such as loss or dysfunction of normal bowel and bladder functions, surgery may be necessary. There is limited evidence to support many treatments such as gabapentin and pregabalin, corticosteroids and acupuncture, heat, ice, and spine manipulation.

According to how sciatica is defined, between 1% and 40% of people will experience it at one time or another. Sciatica is more common in the 40- to 59-year-old age group. Women are more likely to be affected than men. This condition is well-known since ancient times.

Sciatica

Sciatica is generally diagnosed when a person experiences radiating pain in one of their legs and neurological signs such as nerve root tension or neurological deficit.

The most commonly used diagnostic test is the straight-leg raise to produce Lasegue’s sign. This method reproduces the sensation of pain in the sciatic nerve distribution. Passive flexion of the straight legs between 30 and 70 degrees is sufficient to confirm the diagnosis. This test is positive for approximately 90% of people suffering from sciatica. However, 75% of those with positive tests do not suffer from sciatica. Straight raising one leg without sciatica can cause sciatica on the affected leg. This is called the Fajersztajn Sign. Fajersztajn is a more precise sign for a herniated disk than La segues. The problem may be worsened by coughing, neck flexion, and bilateral compressions of the jugular veins.

Pain medication is often used as the first treatment. Evidence for muscle relaxants and pain medication is not available. People should continue to do their normal activities as best they can. Sciatica symptoms often resolve within six weeks. In fact, 90% of patients experience relief in under six weeks.

Sciatica syndrome is a common condition affecting the sciatic nerve, the largest nerve in the body. It originates in the lower back and extends down the back of the leg, branching off into various smaller nerves along the way. This blog post will provide an overview of sciatica syndrome, including its causes, symptoms, and treatment options.

Causes of Sciatica Syndrome

Sciatica syndrome can be caused by a variety of factors, including herniated or bulging discs, spinal stenosis, degenerative disc disease, or trauma to the lower back. It can also be caused by conditions that compress or irritate the sciatic nerve, such as piriformis syndrome, which occurs when the piriformis muscle in the buttocks presses on the sciatic nerve.

Symptoms of Sciatica Syndrome

The symptoms of sciatica syndrome can vary depending on the underlying cause, but typically include pain, numbness, and tingling sensations that radiate from the lower back down the back of one or both legs. The pain can be sharp or dull, and may be accompanied by muscle weakness or difficulty moving the affected leg. In some cases, coughing or sneezing can exacerbate the pain.

Diagnosis of Sciatica Syndrome

To diagnose sciatica syndrome, your doctor will likely perform a physical exam to assess your range of motion and check for areas of tenderness or weakness in the affected leg. They may also order imaging tests, such as an X-ray, MRI, or CT scan, to look for any abnormalities in the spine or surrounding tissues.

Treatment Options for Sciatica Syndrome

The treatment for sciatica syndrome typically involves a combination of rest, physical therapy, and pain management. Your doctor may also recommend nonsteroidal anti-inflammatory drugs (NSAIDs) or other medications to help relieve pain and inflammation.

Physical therapy can be an effective way to help alleviate symptoms and improve mobility. Your therapist may recommend exercises to help stretch and strengthen the muscles in your back, hips, and legs, as well as modalities such as heat or ice therapy or electrical stimulation to help reduce pain and inflammation.

Surgery may sometimes be necessary to relieve pressure on the sciatic nerve. Your doctor will discuss the risks and benefits of surgery with you and help you decide whether it is the right choice for you.

Prevention of Sciatica Syndrome

There are several steps you can take to help prevent sciatica syndrome, including:

  • Maintaining good posture to avoid putting excessive strain on the lower back
  • Engaging in regular exercise to help strengthen the muscles in the back, hips, and legs
  • Using proper lifting techniques to avoid straining the back muscles
  • Taking frequent breaks when performing repetitive tasks that involve the back muscles

In conclusion, sciatica syndrome is a common but potentially debilitating condition that can cause pain, numbness, and tingling sensations in the back and legs. If you are experiencing symptoms of sciatica syndrome, it is important to seek medical attention to ensure an accurate diagnosis and appropriate treatment. With proper rest, physical therapy, and pain management, most people with sciatica syndrome can recover and resume their normal activities.
