Muscle weakness in the legs may indicate a neuromuscular disease is present. These diseases lead to a loss of functioning in nerves and muscles throughout the body. They include muscular dystrophy, amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), myasthenia gravis and fibromyalgia.
Often, the cause of weakness or pain in the legs when walking is a narrowing of the space around nerves that carry signals to the lower part of the body. When symptoms affect your legs, the condition is typically lumbar spinal stenosis.
Too much exercise
Without proper rest, muscles, including those in the lower body, are unable to recover properly. Working out too hard or without proper rest may lead to a feeling of tired, heavy legs. Proper rest reduces the chance of health issues and undue stress on the body.
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.
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.
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.
Weakness in your leg(s) may occur from problems in the nerves and/or muscles in your lower body and is usually treatable. Rarely, the underlying cause may be a serious medical condition requiring immediate medical attention. A feeling of sudden weakness in the legs may be due to nerve and/or muscle dysfunction.
Summary. Weakness in the legs is a common symptom of many health conditions and injuries, including autoimmune diseases, spinal conditions and injuries, and stroke. Often, leg weakness will resolve over time, but in some cases, it can be a medical emergency, especially if the weakness comes on suddenly.
Weakness, leg cramps, or fatigue. Diuretics may decrease the body's levels of the mineral potassium, which can lead to these side effects. Certain potassium-sparing diuretics do not have this effect, however.
Some medicines can cause leg problems. A few examples are: Birth control pills and estrogen. These can increase the risk of blood clots in the leg, which may cause pain or swelling.
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.
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.
People with heart failure have a tendency to retain fluid. This appears as swollen ankles and legs because of excess fluid building up. You may notice that your shoes don't fit and socks appear tight or leave a prominent indent above the ankle.
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. Numbness in your legs or feet when you are at rest. Your legs may also feel cool to the touch, and the skin may look pale.
During exercise, muscles produce metabolites, which are sensed by metaboreceptors that transmit information via fatigue pathways to the brain, according to the researchers. But in patients with SEID, these fatigue pathways have become highly sensitive to metabolites and can trigger excessive feelings of fatigue.
Sarcopenia is the age-related progressive loss of muscle mass and strength. The main symptom of the condition is muscle weakness. Sarcopenia is a type of muscle atrophy primarily caused by the natural aging process. Scientists believe being physically inactive and eating an unhealthy diet can contribute to the disease.
Make an appointment with your health care provider if:
You have pain during or after walking. You have swelling in both legs. Your pain gets worse. Your symptoms don't get better after a few days of treating them at home.
About restless legs syndrome
Restless legs syndrome, also known as Willis-Ekbom disease, is a common condition of the nervous system that causes an overwhelming, irresistible urge to move the legs. It can also cause an unpleasant crawling or creeping sensation in the feet, calves and thighs.
Leg shaking can happen for many reasons, ranging from restless legs syndrome (RLS) to serious conditions such as dementia. It can be a subtle annoyance or an intense experience that causes muscle tension and difficulty walking. It is not possible to diagnose the cause of shaky legs based on symptoms alone.
The main cause of heavy legs is generally poor blood circulation. Blood circulation problems generally occur in the lower part of your body, especially your legs. This is because the lower section of your body needs to fight against gravity to transfer the blood back up to your heart.
"Older people can definitely regain good leg strength if they do regular strengthening exercises and increase the intensity of their exercises in a slow and safe way.
