Weakness in the legs often occurs as a result of overactivity. However, it can sometimes be a sign of an underlying medical condition. A person who experiences sudden weakness in the legs or some other part of their body should seek emergency medical attention.
Leg weakness can be caused by a variety of medical conditions, some of which are serious. Possible causes include stroke, systemic diseases, inflammatory conditions, nerve damage, muscle disorders, and medication side effects.
Issues involving the spinal cord are the most prevalent source of leg weakness. A narrowed spinal canal, or stenosis, puts pressure on the nerves that travel through the spine. You might experience pain, tingling, heaviness or weakness in the legs.
Causes of Leg Fatigue or Heaviness
They include: Varicose veins: The leg veins become enlarged. Peripheral arterial disease (PAD): Buildup of fat deposits in the artery walls, thus, causing inadequate circulation of blood in the legs. Overtraining syndrome: Excess training or physical activities to improve performance.
Combining running and walking with strength training and other forms of aerobic exercise like swimming, elliptical training and cycling can add variety to your workout and can greatly improve your performance. Sports like soccer and basketball are great for improving leg power as well.
The “jelly legs” feeling, which typically refers to feelings of weakness, dizziness, or loss of control in the legs, is often caused by a rush of adrenaline taking blood away from the legs, though there may be other causes.
As a result, people with heart failure often feel weak (especially in their arms and legs), tired and have difficulty performing ordinary activities such as walking, climbing stairs or carrying groceries.
Muscle weakness due to vitamin D deficiency is predominantly of the proximal muscle groups and is manifested by a feeling of heaviness in the legs, tiring easily, and difficulty in mounting stairs and rising from a chair; the deficiency is reversible with supplementation (15–18).
Another common symptom of chronic anxiety is weakness in the muscles, most commonly experienced in the legs and sometimes the arms. During the fight or flight response, the body is preparing to take action against danger.
Causes of nerve damage include direct injury, tumor growth on the spine, prolonged pressure on the spine, and diabetes. A spinal cord injury. Spinal cord injuries are among the most common reasons that legs give out. These injuries vary in severity but should always be evaluated immediately by a spine specialist.
Rising from a squatting position or stepping onto a chair tests proximal leg strength; walking on the heels and on tiptoe tests distal strength. Pushing with the arms to get out of a chair indicates quadriceps weakness. Swinging the body to move the arms indicates shoulder girdle weakness.
Sometimes, leg pain can signal something more serious like a fracture, deep vein thrombosis or compartment syndrome. Seek medical attention urgently if: the leg is swollen. it looks deformed or you can't use it properly.
Vitamin B12deficiency symptoms may include: strange sensations, numbness, or tingling in the hands, legs, or feet. difficulty walking (staggering, balance problems) anemia.
Warning signs and symptoms of heart failure include shortness of breath, chronic coughing or wheezing, swelling, fatigue, loss of appetite, and others. Heart failure means the heart has failed to pump the way it should in order to circulate oxygen-rich blood throughout the body.
Poor Blood Supply to Extremities
Poor blood supply to the legs may lead to: Pain, achiness, fatigue, burning, or discomfort in the muscles of your feet, calves, or thighs. Symptoms that often appear during walking or exercise, and go away after several minutes of rest.
Abnormal sensations can be a common initial symptom of MS. This often takes the form of numbness or tingling in different parts of your body, such as the arms, legs or trunk, which typically spreads out over a few days.
What is weakness in MS? Weakness is a common symptom in multiple sclerosis. You may feel that you do not have enough strength or energy to move some or all of your limbs, or your whole body. Weakness and fatigue are closely linked and having one often makes the other symptoms worse.
Vitamin D helps your body use calcium. But when you're deficient in this vitamin, your legs may feel weak, sore and heavy. A vitamin E deficiency may be another reason your legs feel heavy after a run.
Medical Imaging Tests for Leg Pain
MRI Scan of the Spine, Computerized Tomography (CT) Scan, ultrasound, or plain x-rays are typically used while diagnosing leg pain. Imaging tests help identify herniated discs, abnormal bone growths (bone spurs), bone fractures, and tumors among others.
Doctors use a blood test to look for elevated levels of a substance called creatine kinase, which is released into the bloodstream when muscle fibers deteriorate. Elevated levels may mean you have an inflammatory myopathy.
