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.
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.
People will often experience shaky or weak legs when dealing with vascular issues in the leg, like deep vein thrombosis or blood clots. Clots are very serious if untreated because they could break off into the bloodstream and travel to an artery in the lungs, blocking blood flow.
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.
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.

However, tremors and other movement disorders are associated with vitamin deficiency, most vitamins B1, B6 and especially B12. B12 is very important for keeping your nervous system in good working order. Severe lack of Vitamin B12 is rare, but shakiness and tremors can occur even in mild deficiency.
Diabetes and atherosclerosis are the main causes of poor circulation in the body, but are also associated with smoking, living an inactive lifestyle, or having high blood pressure or cholesterol.

The nerves outside of your brain and spinal cord can become damaged, which is called peripheral neuropathy. Weakness, numbness, pain and balance issues can be caused by peripheral neuropathy because it makes it difficult to determine where your body is relative to other objects or the ground.
In fact, stress and chronic stress often cause heavy, tired, jelly-like, rubbery, weak, and stiff legs feelings because of how stress affects the body's muscles, including those in the legs.
Vitamin D, magnesium, and calcium are all quite important for building bones and muscle tissue. Moreover, vitamin D deficiencies are exceedingly common among the elderly, and research has clarified that correcting that deficiency with supplements can help improve a person's strength.
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.
