It’s normal to feel temporary leg numbness after sitting too long or crossing your legs, and in most cases, the sensation disappears once you move. However, if the numbness persists, happens frequently, or worsens over time, it could signal more than just poor circulation. In some cases, it may be linked to an underlying spine condition that needs medical attention. Understanding the connection between spine health and leg numbness can help you spot early warning signs and take action before the issue worsens.
Read on to learn about the common spinal conditions that could be causing your symptoms.
How Spine Issues Cause Leg Numbness
The spine houses the spinal cord and nerve roots, which control sensation and movement in the legs. When these nerves are compressed, irritated, or damaged, it can lead to numbness, tingling, or even weakness in the lower limbs. Common spinal conditions that cause leg numbness include:
Herniated Disc (Slipped Disc)
A herniated disc occurs when the soft inner portion of a spinal disc pushes out, pressing on nearby nerves. If this happens in the lower back (lumbar spine), it can compress the sciatic nerve, leading to numbness, tingling, or pain in the legs and feet.
Spinal Stenosis
Spinal stenosis refers to the narrowing of the spinal canal, which can put pressure on the nerves responsible for leg function. Patients with lumbar stenosis may experience numbness, weakness, or heaviness in the legs, especially after walking or standing for long periods.
Sciatica
Sciatica is a condition caused by irritation or compression of the sciatic nerve, which runs from the lower back down both legs. This often results in sharp pain, numbness, or a “pins and needles” sensation along the back of the thigh and calf.
Spondylolisthesis
In spondylolisthesis, one vertebra slips forward over another, leading to spinal instability and nerve compression. This can cause leg numbness, pain, or weakness, particularly when standing or walking.
Degenerative Disc Disease
As the spinal discs wear down over time, they lose their cushioning ability, leading to inflammation and nerve irritation. This degeneration can contribute to chronic lower back pain and intermittent leg numbness.
When to See a Spine Specialist
If you experience persistent leg numbness, weakness, or loss of coordination, it’s crucial to consult a spine and orthopaedic specialist. Early diagnosis and treatment can prevent worsening symptoms and improve mobility.
Symptoms to look out for:
- Persistent or worsening lower back pain (sharp, dull, burning and/or aching)
- Features of neurological involvement (pain. Numbness, weakness or tingling in the lower limb)
- Changes in the bowel and bladder function
