What Causes Numbness in One Leg?
Numbness in one leg can be a distressing experience. It may start as a tingling sensation, often described as pins and needles in legs, or lead to complete loss of feeling in legs. While temporary numbness might not be a red flag, frequent numbness in legs, particularly when it affects only one leg, could signal deeper neurological or vascular issues.
At King’s Spine Centre, we specialize in diagnosing and treating numbness in one leg, whether it’s right leg numbness, left leg numbness, lower leg numbness, or numbness in the calf and foot.
Understanding Numbness in One Leg
What Is Numbness in One Leg?
Numbness in one leg refers to a sudden loss of sensation, tingling numbness in legs, or numb feeling in legs that occurs either temporarily or persistently. It often affects the right leg or left leg only, and can involve the entire leg, lower leg, or just the foot and calf. This symptom can result from issues with nerves, blood flow, or even posture.
What Causes Numbness in One Leg?
There are many potential causes of numbness in one leg, ranging from minor to serious conditions. Here are some of the most common:
Nerve Compression
Nerve compression is one of the main causes of numbness in one leg. Conditions such as sciatica or a herniated disc can exert pressure on nerves, resulting in a tingling or numbing sensation.
- Sciatica: The sciatic nerve runs through each leg from the lower back down. Compression or irritation of the sciatic nerve is a leading cause of numbness in right leg or numbness in left leg. It often causes shooting pain down the leg and muscle weakness.
- Herniated Disc: A bulging (slipped) disc in the spine can put pressure on the nerves, leading to leg numbness and tingling, especially in one leg only. This condition is often accompanied by lower back pain.
Circulatory Problems
Restricted blood flow can also lead to numbness in one leg. Poor circulation deprives the tissues and nerves of oxygen, causing temporary or prolonged numbness.
- Peripheral Artery Disease (PAD): Narrowed arteries reduce blood flow, causing legs going numb, cramping, and fatigue.
- Deep Vein Thrombosis (DVT): A blood clot can obstruct circulation, leading to leg numbness, swelling, and even life-threatening complications.
Injury or Trauma
Direct injury can damage nerves or restrict blood supply, causing numbness in left leg below knee, right leg numbness, or calf numbness.
Medical Conditions
Several medical conditions are associated with numbness in one leg:
- Diabetes: Diabetic neuropathy damages the peripheral nerves, often starting as tingling in legs and progressing to no sensation in legs.
- Multiple Sclerosis (MS): This neurological condition affects the brain and spinal cord, producing symptoms like leg feels numb, tingles in legs, or numbness on right leg or left leg.
Lifestyle Factors
Certain habits or postures can contribute to temporary numbness:
- Prolonged Sitting or Standing: Can compress nerves, leading to legs going numb when standing or leg going numb while sitting.
- Vitamin Deficiencies: Low levels of essential vitamins, such as B12, can weaken nerves and may result in numbing of legs and tingly legs.
Symptoms Associated with Numbness in One Leg
Numbness in one leg is often accompanied by additional symptoms, including:
- Tingling in one leg (pins and needles)
- Muscle weakness or heaviness
- Difficulty moving the leg or foot
- Pain or discomfort in the lower back, hip, or thigh
- Leg feels numb and tingly, especially when lying down or sitting
If you notice any of these symptoms, it’s critical to seek medical advice to prevent the condition from worsening.

- Physical Examination: Testing reflexes, strength, and sensation to evaluate nerve function.
- Imaging Tests: MRIs, X-rays and CT scans help identify structural issues like herniated discs or compressed nerves.
- Electromyography (EMG): Electromyography (EMG) evaluates nerve signal activity to find numbness leg sources.
Treatment Options for Numbness in One Leg
The treatment for numbness in one leg depends on the underlying cause. At King’s Spine Centre, we provide tailored solutions, including:
- Physical Therapy
- Targeted exercises to improve strength, flexibility, and nerve function.
- Medications

- Lifestyle Modifications
- Recommendations on posture, ergonomic adjustments, and dietary changes to prevent recurrence.
When Should You Worry About Leg Numbness?
While occasional numbness may not be serious, certain signs exhibit the need for immediate medical attention:
- You have persistent numbness in one leg.
- There’s sudden leg numbness with pain or swelling.
- You experience loss of feeling in legs or difficulty walking.
- You’re seeing numbness in one leg while walking, or numbness in both legs suddenly.
