Symptoms that sometimes accompany leg weakness include a prickling feeling, paralysis, numbness, muscle spasms or a burning sensation, reports Healthgrades. Some people with leg weakness also experience a twitching, red, warm or swollen leg. A general sick feeling, body aches and back pain are accompanying symptoms that affect other parts of the body.

Compared to leg weakness that is part of a general feeling of bodily weakness, true leg weakness involves the loss of muscle function and results from injury, neuromuscular disease, poisoning or life-threatening condition such as stroke, explains Healthgrades. People with leg weakness sometimes experience a tingling sensation in the hands or feet, lack of muscle coordination, or loss of balance.

Leg weakness sometimes occurs due to a condition affecting the spinal cord, such as injury, a herniated disc or spinal arthritis, states Healthgrades. The common symptoms of these spinal conditions include leg weakness accompanied by pain or a tingling, numb or burning sensation. Trauma in the form of sprains, strains and fractures also sometimes causes weak legs.

Sudden leg weakness that occurs only on one side of the body likely signals stroke and requires emergency medical care, notes Healthgrades. Leg weakness accompanied by vision problems, paralysis, numbness or intense headache also requires immediate medical attention.
