What Are The Causes of Sudden Leg Weakness?

November 13, 2019


A sense of sudden weakness of the legs may be alarming, causing them to give out or buckle. Your leg(s) may be weak due to issues in your reduced body’s nerves and/or muscles and is generally treatable. There could be a need of instant medical attention in a pain clinic in OKC to know the underlying cause.


You may experience symptoms of radiculopathy in your leg when nerve roots are compressed between L1 and S3 in your spine. The sciatic nerve (shaped by the L4-S1 nerve roots) is the most prevalent form of radiculopathy and is called sciatica. Sciatica is usually felt as shooting pain that begins in the back and radiates into the foot through the back of the leg.

Other symptoms of radiculopathy may include weakness of the arm, heaviness, and/or function loss. Typically, radicular disease impacts one leg at a moment. In the impacted arm, you may also experience pain, numbness, and/or tingling. Higher compression of the nerve root (L1-L3) may influence the thigh and groin front.

Central canal stenosis

Spinal canal narrowing is called core canal stenosis. The spinal canal houses the cord of the spinal cord. Central stenosis of the canal can cause the spinal cord to compress and decrease its blood supply. This canal may be narrowed in the neck, upper back and/or lower back. In adults, the spinal cord ends at L1. Stenosis below this stage is not caused by cord compression, but by nerve roots compression.

Due to disc herniation, an abnormally overgrown bone, or thick spinal ligaments, central canal stenosis may occur. Other causes like trauma and spine-growing tumors are also found.

Diabetic Neuropathy

Diabetes mellitus may harm your legs and feet’s nerves and muscles. Typically, these nerves receive less blood supply in diabetes, which damages their structure. Diabetic neuropathy also considerably reduces muscle power and thickness, leading to leg weakness.

A few common symptoms –

  • Leg and ankle weakness

  • Lacking in balance and pace

  • Burning or sharp pain

  • Numbness or no sensation in leg and feet

Preventing Tired Legs

To avoid or decrease your danger of tired legs, there are some things you can do:

  • Eat a balanced, healthy diet to guarantee that your recommended daily nutrient levels are obtained. This helps give you the energy you need to carry out your daily tasks.

  • Get plenty of vitamin D from your diet or direct sun exposure.

  • Wear the right footwear, particularly if you’re going to be long on your feet. Choose a supportive, comfortable and properly fitting shoe. For further assistance, add padded insoles.

  • Get up and move as frequently as possible. Strive to practice for at least 15 minutes each day. For each hour you are sedentary, move around or stretch for at least five minutes.

  • Keep uncrossed your legs while sitting.

  • Sit or stand tall, keep a healthy posture.

  • Get plenty of water to drink.

  • Keep the optimum weight.

  • Sleep with pillows under your feet.

  • Take good rest.

  • Alcohol, sugar and caffeine should be limited or avoided.

  • Stop smoking if you smoke.

When to Ask for Help

Usually, in relieving tired legs, rest and home remedies will be efficient. However, if after at-home therapy your legs still feel tired or if the tiredness has continued for more than a few days, create an appointment with your doctor.

If you experience any pain, dysfunction, or discomfort, see your physician as well. Your physician can determine if your legs are tired of an underlying illness.
