Sciatica: Symptoms, Causes, Diagnosis, Treatment and Recovery

Sciatica is a common condition that can cause pain, tingling, numbness or weakness travelling from the lower back or buttock into the leg. Although the symptoms are often felt in the leg, they are usually related to irritation or compression of a nerve root in the lower back.

Sciatica can be extremely uncomfortable and, in some cases, can make walking, sitting, working or exercising difficult. The good news is that most people improve with time and appropriate conservative management, and surgery is not required for most cases.

At Pipers Physiotherapy, we assess and treat people with sciatica and other lower-back and nerve-related conditions. Our aim is to help you understand your symptoms, restore movement and function, and develop a rehabilitation plan around your individual goals.

What is sciatica?

Sciatica describes symptoms caused by irritation or compression of one or more of the nerves or nerve roots that contribute to the sciatic nerve.

The sciatic nerve is a large nerve that travels from the lower back, through the buttocks and down the back of the leg. Sciatic-type symptoms commonly affect one side of the body and may extend into the foot and toes.

Sciatica is different from ordinary lower-back pain. The main feature is usually pain or other nerve-related symptoms travelling into the leg. You may have back pain at the same time, but the leg symptoms are often more noticeable.

Symptoms can include:

• Sharp or shooting pain

• Burning pain

• Tingling or pins and needles

• Numbness

• Weakness in the leg or foot

Symptoms can vary considerably between people and may change over time.

What causes sciatica?

There are several possible causes of sciatica.

One of the most common causes of sciatica is a herniated or prolapsed disc. The discs sit between the bones of the spine and act as cushions. If part of a disc protrudes, it can irritate or compress a nearby nerve root and cause symptoms travelling into the leg. Other possible causes include:

• Herniated or prolapsed disc: A disc can bulge or protrude and irritate a nearby nerve root. This is one of the most common causes of sciatica.

• Spinal stenosis: Spinal stenosis occurs when there is narrowing around the spinal canal or the openings through which the spinal nerves pass. This can reduce the available space around the nerves and sometimes cause leg symptoms.

• Spondylolisthesis: Spondylolisthesis occurs when one vertebra moves relative to another. In some cases, this can contribute to narrowing around a nerve and produce sciatic-type symptoms.

• Back injuries: Trauma or injury to the spine can occasionally affect the structures surrounding the spinal nerves.

• Deep gluteal syndrome:  Irritation or compression of the sciatic nerve within the deep tissues of the buttock. This is considerably less common than nerve-root irritation originating from the lower spine.

• Other causes: Much less commonly, symptoms resembling sciatica can be associated with conditions such as infection, inflammatory disease, tumours or other spinal problems. These conditions are uncommon, but your physiotherapist will consider your medical history and symptoms to identify whether further assessment is required.

What are the symptoms of sciatica?

Sciatica symptoms can range from mild irritation to severe pain that significantly affects everyday life. Common symptoms often include pain travelling from the lower back or buttock into the back of the thigh and lower leg. However, the exact location depends on which nerve structures are affected.

Common symptoms include:

• Leg pain: Sciatic pain is often described as sharp, shooting, burning or electric. It commonly travels down one leg and may extend into the foot.

• Tingling and pins and needles: You may experience tingling or a pins-and-needles sensation anywhere along the affected nerve pathway.

• Numbness: Some people experience reduced sensation in part of their leg, foot or toes.

• Weakness: Nerve irritation can sometimes affect the muscles supplied by the affected nerve, causing weakness in the leg or foot.

• Back and buttock pain: You may also experience lower-back or buttock pain, although the leg symptoms can sometimes be more troublesome than the back pain.

• Symptoms affected by movement: Some people find that their symptoms become worse with sitting, bending, coughing or sneezing. Others find that changing position or gentle movement provides some relief. The pattern varies depending on the underlying cause.

When should you seek urgent medical attention?

Most cases of sciatica are not an emergency. However, certain symptoms require urgent medical assessment.

Seek emergency medical attention if you develop:

• Numbness around the genitals, anus or the area between your legs

• Difficulty starting urination or inability to urinate

• Loss of control of your bladder

• Loss of control of your bowel

• Severe or worsening weakness or numbness in both legs

• Sciatica affecting both legs, particularly when associated with neurological symptoms

These can be warning signs of cauda equina syndrome, a rare but serious condition caused by compression of the nerves at the bottom of the spinal canal. Prompt assessment and treatment are important.

If you are experiencing these symptoms, seek emergency medical attention rather than waiting for a routine physiotherapy appointment.

How is sciatica diagnosed?

Sciatica is usually diagnosed through a combination of your symptoms, medical history and physical examination. Your physiotherapist will ask about how your symptoms started, where your pain travels, and whether you have any numbness, tingling or weakness. They may assess your spinal and leg movement, muscle strength, sensation, reflexes and nerve sensitivity. Specific tests, such as the straight-leg raise, may also be used.

This assessment helps determine whether your symptoms are consistent with sciatica and whether further investigation or medical assessment is needed.

How is sciatica treated?

The good news is that most people with sciatica improve over several weeks to a few months, although some people experience symptoms for longer or have recurrent episodes.

Treatment should be tailored to your symptoms, examination findings, lifestyle and goals.

Physiotherapy can play an important role in helping you manage sciatica and return to your normal activities. Your physiotherapist may help you with:

• Understanding your symptoms

• Managing pain and activity

• Maintaining or restoring movement

• Developing an appropriate exercise programme

• Improving strength and physical capacity

• Gradually returning to work, exercise or sport

• Developing strategies to manage future flare-ups

  
  

Rather than simply treating the painful area, rehabilitation considers how your symptoms are affecting your overall movement and function.

How can physiotherapy help with sciatica?

At Pipers Physiotherapy, we take an individualised approach to the assessment and management of sciatica. Your physiotherapist will first establish what is likely to be causing your symptoms and assess for any signs that require further medical investigation.

Your rehabilitation programme may then focus on:

• Reducing the impact of your symptoms

• Restoring spinal and hip movement

• Improving strength and physical capacity

• Gradually increasing your activity

• Returning to work or exercise

• Returning to running or sport where appropriate

• Helping you understand how to manage future flare-ups

  
  

The exact treatment will depend on your symptoms and assessment rather than following a single treatment protocol.

Conclusion

Sciatica can cause significant pain, tingling, numbness or weakness travelling from the lower back or buttock into the leg. Although it can be extremely painful, most people improve without surgery.

A thorough assessment can help establish whether your symptoms are consistent with sciatica, identify any neurological involvement and determine whether further investigation is necessary.

Exercise, maintaining appropriate activity and education are important parts of managing sciatica. Physiotherapy can help you gradually restore movement, strength and confidence while returning to the activities that matter to you.

At Pipers Physiotherapy, we can assess your symptoms and develop an individualised rehabilitation programme based on your condition, lifestyle and goals. Whether you want to return to work, get back to exercise, resume running or simply be able to walk and sit comfortably again, our aim is to help you move forward with confidence.
