Why Do My Legs Keep Going Numb?

Why Do My Legs Keep Going Numb?

When you sit too long in one place, you might notice it’s difficult to walk again because your legs feel numb and tingly. If you experience leg numbness often, it’s time to schedule a visit with your doctor. Frequent leg numbness may be a sign that something more serious is wrong.

At The Institute for Comprehensive Spine Care, world-class spine surgeon Gbolahan Okubadejo, MD, FAAOS, offers specialized treatments for serious spine conditions that can lead to chronic numbness in your legs and feet. Dr. Bo recommends seeking treatment sooner rather than later to prevent more serious complications down the road.

Possible causes of leg numbness

There are several reasons why you might develop numbness in your legs. In many cases, the issue is a temporary one.

If you sit with your legs crossed or practice poor posture, you might be reducing blood flow to your lower limbs that causes weakness, numbness, and tingling sensations (pins and needles). You can also cut off the blood supply to your legs and feet if you wear pants or socks that are too tight.

Leg numbness can also be a warning sign of more serious conditions like:


Sciatica describes a jolting, shock-like pain in the lower back because of pressure on the sciatic nerve, the large nerve that provides sensations to your lower limbs.

Pressure from a herniated disc, bone spur, or spinal stenosis can cause pain to radiate into any of the areas the nerve travels, including your hips, legs, and feet. Pain can become chronic and severe, especially when you make sudden movements like a cough, laugh, or sneeze.

Peripheral artery disease (PAD)

PAD describes a condition where blockages reduce blood flow in your peripheral arteries.

Getting older, smoking, and too much cholesterol can all narrow the arteries and cause weakness and numbness in your legs because of poor blood circulation.

Abnormal growths

Benign (noncancerous) or malignant (cancerous) tumors on your spinal cord or brain can reduce blood flow in your lower limbs.

As pressure from these growths continues, you may experience numbness, tingling, and weakness in your lower back, legs, and feet.


Uncontrolled diabetes can cause damage in the nerves of your legs, feet, and spine over time, a condition known as diabetic neuropathy.

Without treatment, permanent nerve damage can occur that causes you to lose feeling in your legs and feet. This can allow sores to form unnoticed in these areas, leading to serious infection, tissue death, and the need for amputation.

Get help early for leg numbness

It’s important that you identify what’s causing your leg numbness as early as possible. With the right treatment, you can improve the health of your legs and preserve their function in the long-term.

The diagnostic testing services Dr. Bo offers can help confirm or rule out issues that are causing numbness in your leg. We also offer comprehensive and customized treatment plans that address spine-related causes of leg numbness including herniated discs, sciatica, and tumors.

Dr. Bo initially focuses on conservative therapies to stop leg numbness. However, he is also highly skilled in minimally invasive surgical techniques to address the root cause of numbness and pain, so you can enjoy a more active lifestyle.
