What is Sciatica?
Sciatica is a condition characterized by pain that radiates along the sciatic nerve, which runs from the lower back down the back of each leg. Sciatica is typically caused by a problem with the sciatic nerve, such as a herniated disc, spinal stenosis, or a degenerative disc disease.
Sciatica can be a debilitating condition and can greatly impact a person’s quality of life. It’s important to see a doctor if you have symptoms of sciatica, as they can help determine the underlying cause and develop an appropriate treatment plan.
Common symptoms of Sciatica
The most common symptoms of sciatica include:
- Pain that radiates from the lower back down one or both legs. This pain can be described as a sharp or burning sensation and may be accompanied by numbness, tingling, or weakness in the affected leg or foot.
- Shooting pain that makes it difficult to stand, sit, or walk. Some people experience a constant ache in the affected leg or a cramping sensation.
- Low back pain and muscle spasms, particularly in the lower back and hip area.
- Tingling or “pins and needles” feeling in the affected leg.
- Numbness or weakness in the affected leg or foot. This can make it difficult to move the affected leg or foot.
- Difficulty in performing activities such as standing up, walking, or sitting down due to pain.
It’s important to note that not all people will experience the same symptoms and the severity of symptoms can vary widely between individuals. Some people may experience mild discomfort, while others may have severe pain that makes it difficult to perform daily activities.
Sciatica can be caused by a variety of conditions, including herniated disks, spinal stenosis, and degenerative disc disease. It’s important to see a healthcare provider if you have symptoms of sciatica, as they can help determine the underlying cause and develop an appropriate treatment plan.
Causes of Sciatica
Sciatica is caused by irritation or compression of the sciatic nerve. The sciatic nerve is the largest nerve in the body and runs from the lower back down the back of each leg. Sciatica can be caused by a variety of conditions that affect the sciatic nerve, such as:
- Herniated disk: A herniated disk occurs when the soft center of a disk in the spine bulges out, putting pressure on the sciatic nerve.
- Spinal stenosis: Spinal stenosis is a condition in which the spinal canal becomes narrowed, putting pressure on the nerve roots, including the sciatic nerve.
- Degenerative disc disease: Degenerative disc disease occurs when the disks in the spine break down, which can lead to narrowing of the spinal canal, putting pressure on the nerve roots and causing sciatica.
- Spondylolisthesis: is a condition where one vertebral body slips forward over another one, usually putting pressure on nerve roots or the spinal cord
- Piriformis syndrome: is a condition in which the piriformis muscle irritates the sciatic nerve causing pain and symptoms similar to sciatica.
- Other causes: tumors, infections, pregnancy etc can also cause sciatica.
It’s important to note that in some cases, the underlying cause of sciatica may not be able to be identified. It’s important to see a healthcare provider if you have symptoms of sciatica, as they can help determine the underlying cause and develop an appropriate treatment plan.
How is Sciatica assessed by a Physiotherapist?
A physiotherapist can perform a thorough assessment to determine the cause of your sciatica and develop an appropriate treatment plan. The assessment typically includes:
- Patient history: The physiotherapist will take a detailed history of your symptoms, including when your sciatica started, how often it occurs, and what makes it worse or better. They will also ask about any other relevant information, such as your medical history, medications you are taking, and any previous treatments you have tried.
- Physical examination: The physiotherapist will perform a physical examination to check for any abnormalities or problems that could be causing your sciatica. They will evaluate your posture, gait, range of motion in your back, hips and legs and the strength and tone of the muscles that support your back. They will also look for any tenderness or pain in these areas, or any other areas that may be contributing to your sciatica.
- Special Tests: Depending on the signs and symptoms, physiotherapist may conduct special tests to find out the specific cause of sciatica. Eg: Straight leg raise test, Slump test, Patrick’s test for lumbar disc herniation, Femoral nerve tension test for Lumbar stenosis.
- Imaging: The physiotherapist may refer you to have an imaging such as X-ray, MRI or CT scan to confirm or rule out any specific diagnosis.
Based on the findings of the assessment, the physiotherapist can then develop a treatment plan that may include a combination of manual therapy, exercises, education on posture and ergonomics and also advise on lifestyle changes that can help to reduce the frequency and intensity of your sciatica. The physiotherapist will also work closely with other healthcare professionals, such as doctors and surgeons, to ensure an effective and efficient management of your condition.
Treatment for Sciatica
Treatment for sciatica typically begins with non-surgical options, such as over-the-counter pain medication, hot or cold compresses, and physical therapy. These methods can help to reduce inflammation and pain, and improve muscle strength and flexibility.
Physical therapy exercises can include stretching, strengthening, and low-impact aerobics. These exercises are designed to improve flexibility, reduce muscle imbalances, and decrease pressure on the sciatic nerve.
If these non-surgical options do not provide adequate relief, a doctor may recommend an epidural steroid injection, which can help to reduce inflammation and pain. In rare cases, surgery may be necessary to relieve pressure on the sciatic nerve.
It’s important to note that specific treatment will depend on the underlying cause of the sciatica, so it’s important to get a proper diagnosis from a medical professional for best treatment.
Dangers if left untreated
If left untreated, sciatica can lead to a number of complications. Here are a few examples:
- Chronic pain: Sciatica can cause chronic pain in the lower back, hips, and legs, which can make it difficult to perform everyday activities and can negatively impact a person’s quality of life.
- Weakness and numbness: The sciatic nerve controls the muscles in the legs and feet, and if it becomes compressed, it can lead to weakness and numbness in these areas. If left untreated, these symptoms can become worse over time.
- Loss of muscle mass: If the sciatica is causing chronic pain, it can prevent a person from exercising and staying active, which can lead to muscle loss and weakness.
- Loss of bladder or bowel control: In rare cases, severe sciatica can cause damage to the nerve fibers that control the bladder and bowel, which can result in loss of control over these functions.
- Chronic disability: When sciatica is not treated, and progressive, it can lead to chronic disability and affect a person’s work and personal life.
It’s important to seek treatment as soon as possible if you suspect you have sciatica. A medical professional can help determine the underlying cause and provide appropriate treatment to help prevent complications.
