Sciatica and lower back pain radiating to the leg

Lower back pain radiating to the leg is a common complaint. Many people experience pain in the lower back that radiates to the buttock, thigh, lower leg, or even the foot. This is often referred to as sciatica or nerve pain originating from the lower back.

Although the symptoms can vary in intensity, they often have a major impact on daily functioning. Examples include difficulty sitting, standing, walking, or sleeping.

What exactly is sciatica?

Sciatica is a collective term for symptoms that arise when the sciatic nerve becomes irritated. This nerve runs from the lower back through the pelvis and buttocks to the leg and foot.

When this nerve is compressed or becomes irritated, it can lead to lower back pain, radiating pain to the leg, tingling, numbness, or sometimes loss of strength.

Lower back pain radiating to the leg

Not every radiating pain in the leg means that there is “true sciatica”. The symptoms can also arise from tension in the muscles of the lower back or buttocks, reduced mobility of the lower back or pelvis, or irritation of structures in this area.

As a result, pain can manifest in various ways. Sometimes primarily as lower back pain, sometimes more in the buttock, and sometimes as a pulling or radiating sensation towards the leg. Tingling or numbness may also occur.

Because these complaints can overlap, it is important not only to look at the location of the pain, but at the body as a whole and how structures work together.

Possible causes of radiating pain

Lower back pain radiating to the leg is usually caused by a combination of factors that often reinforce each other.

In today's society, prolonged sitting plays a major role in this. Many people have office jobs or spend long periods behind a computer, causing the lower back and pelvis to remain in the same position for extended periods. This can lead to increased tension in the muscles surrounding the lower back and gluteal region, which in turn can affect surrounding structures, including the sciatic nerve.

When this nerve comes under pressure or becomes irritated, it can cause radiating pain down the leg. This can manifest as a pulling, aching, or sharp sensation in the buttock, thigh, or further down the lower leg.

In addition to muscle tension, the mobility of the lower back and pelvis also plays an important role. When these areas move less freely due to, for example, prolonged sitting or a one-sided posture, the load on the area can increase. This makes the tissue more sensitive and can perpetuate symptoms.

In some cases, the intervertebral disc also plays a role. When it becomes overloaded or irritated, this can put extra pressure on nerve structures in the lower back.

Finally, daily strain and posture play an important role in the development and maintenance of the complaints. Prolonged sitting, repeated bending, lifting, or unilateral strain can prevent the system from recovering sufficiently, causing complaints to persist or recur.

What can you do yourself?

In most cases of lower back pain, it is important to stay active. Prolonged rest is generally advised against, as this can lead to stiffness and delayed recovery.

The goal is to keep the body active within the pain threshold, without forcing it. Variation in posture and load plays a more important role in this than complete rest or, conversely, overloading.

When is testing advisable?

It is advisable to have the symptoms assessed if they persist for a longer period or recur. It is also worthwhile to investigate further if there is clear radiation to the leg, or if tingling, changes in sensation, or loss of strength occur.

When symptoms affect work, sleep, or daily activities, that is also a signal that there may be more going on than just temporary irritation.

A thorough analysis helps to gain insight into the underlying cause and which factors perpetuate the symptoms. Based on this, a targeted treatment plan can be drawn up.

Osteopathy for sciatica and lower back pain

Within osteopathy, lower back pain radiating to the leg is approached from the perspective that the body functions as a whole. Therefore, the focus lies not only on the location where the pain is felt, but primarily on the underlying factors that influence the load on this system.

The sciatic nerve runs from the lower back through the pelvis and buttock to the leg. When tension, irritation, or reduced space develops along this path, it can lead to increased sensitivity of the nerve.

During the examination, the mobility of the lower back, pelvis, and hips is assessed. When these structures move less smoothly, this can lead to an altered load distribution in the area, which affects nerve function.

The tension in the muscles and connective tissue surrounding the lower back and gluteal region is also assessed. Increased tension in these structures can increase local load and further restrict mobility.

Because this region works closely with the rest of the body, the abdominal region is often included in the examination. This area contains many organs that are connected via nerve pathways to the same segments of the spinal cord as the lower back. As a result, pain originating from the abdomen can not only be felt locally but also perceived as so-called referred pain in the lower back or surrounding areas. This means that the brain may experience the pain in a different location than where the actual stimulus originates.

Finally, the way in which the nervous system and surrounding tissues work together during movement and loading is examined to gain a complete picture of the factors that perpetuate the symptoms.

What does scientific research say?

Research into osteopathic treatment for lower back pain shows that patients often experience a clear improvement in pain and daily functioning.

In a randomized controlled study of osteopathic treatment for chronic low back pain (Licciardone et al., Annals of Family Medicine, 2013), it was found that a proportion of patients experienced a clinically relevant reduction in pain, often around or above 30%, along with a marked improvement in movement, sitting, and daily activities.

What stands out most is that this improvement is not just about less pain, but primarily about being able to function better in daily life.

Compared to standard care, which usually consists of pain relief, exercise therapy, and waiting for the natural course of the condition, a more consistent effect on pain and mobility was observed in the osteopathy group. With standard care, recovery is often more gradual and dependent on time, load, and individual factors.

Did you know?

The sciatic nerve is the largest nerve in the body and runs from the lower back all the way to the foot. Because this nerve covers such a large area, irritation in one spot can cause symptoms in multiple places in the leg.
