That prickly, tingly legs sensation, often described as “pins and needles,” is something almost everyone feels once in a while. Usually it’s harmless, caused by sitting cross-legged too long or awkwardly leaning on your leg. But when tingly legs become frequent, don’t go away or show up alongside other symptoms, it may be a sign that something is putting pressure on a nerve in your spine.

“Tingling often means a nerve is being compressed or irritated somewhere along its path,” said Nathaniel R. Toop, M.D., neurosurgeon and spine surgeon with Norton Leatherman Spine. “If it’s happening regularly or not going away, it’s worth having it checked out rather than waiting to see if it resolves on its own.”

What causes tingling in the legs?

Tingling in the legs can happen when a nerve’s signal gets interrupted or irritated.

Common causes of tingly legs include:

• Temporary nerve compression from sitting, sleeping in an awkward position, or crossing your legs: This resolves on its own within minutes.
• Sciatica is irritation of the sciatic nerve, often from a herniated disc, that can cause tingling running from the lower back through the hip and down one leg.
• Spinal stenosis is a narrowing of the spinal canal that puts pressure on nerves; it is common with age-related wear and tear.
• Peripheral neuropathy describes nerve damage often linked to diabetes, vitamin deficiencies or certain medications.
• Herniated or bulging discs can cause tingling when the cushioning between spinal bones presses on nearby nerves.

Is tingling in your legs serious?

Occasional tingling that fades quickly usually isn’t cause for concern. But tingling that’s persistent, worsening or paired with other symptoms could point to nerve compression in the spine that needs evaluation.

Seek medical care if your leg tingling comes with:

• Weakness or heaviness in the leg
• Numbness that’s spreading or doesn’t improve
• Pain that radiates from your lower back down your leg
• Loss of bladder or bowel control (seek emergency care immediately)
• Tingling that started after an injury

How to find the cause of tingly legs

A spine specialist typically starts with a conversation about your symptoms: when the tingling started, whether it comes and goes, and if certain positions make it better or worse.

From there, a physical exam checking reflexes, strength and sensation helps narrow down the cause. Imaging such as an MRI or CT scan may be ordered if a nerve compression issue, like a herniated disc or spinal stenosis, is suspected.

Treatment options for tingling legs

Treatment depends entirely on what’s causing the sensation. Treatment options for tingly legs can include:

• Physical therapy to relieve pressure on the nerve and strengthen supporting muscles
• Anti-inflammatory medication to reduce nerve irritation
• Steroid injections for more targeted relief
• Activity modification to avoid positions that aggravate symptoms
• Surgical treatment, in cases where conservative care doesn’t resolve nerve compression

Many people find relief with nonsurgical treatment. For those with more advanced nerve compression, minimally invasive spine procedures can relieve pressure and help restore normal sensation.

When to see a spine specialist

If tingling in your legs is new, recurring or interfering with daily life, it’s worth having it evaluated rather than waiting to see if it goes away. Left untreated, ongoing nerve compression potentially can lead to permanent nerve damage.

A spine specialist can determine whether your symptoms stem from your back or something else entirely, and start building a treatment plan suited to your needs.
