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.
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.
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.
Feeling weakness in one or both of your legs is called monoparesis or paraparesis and can be a direct result of MS. You can also feel weakness in your arms and other areas of your body, but to feel it in your legs often occurs more frequently.
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. Weakness in one or both legs (called monoparesis or paraparesis) can cause problems with walking and balance.
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.
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.
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.
Even if you can identify a cause, you still might need to see a doctor if you aren't getting better. “If you have muscle weakness or fatigue that persists for more than two weeks, it can be something else going on in your system,” Scott said. Another red flag is if healthy changes don't bring relief.
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.
Most can expect to see noticeable muscle growth within eight weeks of starting a new strength training routine. Linking this with aches/pains/injuries when seeing your Physiotherapist, most people look for a quick fix and once they are out of pain then they think they are cured.
Muscle spasms: They usually affect your leg muscles. They're an early symptom for almost half the people with MS. They also affect people with progressive MS. You might feel mild stiffness or strong, painful spasms.
How to self-assess multiple sclerosis symptoms. A multiple sclerosis (MS) self-assessment cannot diagnose MS, but it may help a person understand their symptoms and know when to contact a doctor. An MS self-assessment may focus on energy levels, physical sensations, vision problems, and more.
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.
Tightness or stiffness of the muscles, called spasticity, is caused directly by MS. Spasticity, will alter walking and cause pulling on the joints. This can result in pain typically in the ankles, knees, hips and back.
Magnesium supplementation is often suggested for restless legs syndrome (RLS) or period limb movement disorder (PLMD) based on anecdotal evidence that it relieves symptoms and because it is also commonly recommended for leg cramps.
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.
