Frequent tingling in the legs can be more than simply a little annoying. You might start to worry about the cause of this sensation and whether it is dangerous to your health.
Our vein specialists tell you everything you need to know about tingling in the legs including the common causes and what this means for your health.
We’ve all felt it, that familiar tingling, numbing feeling in the leg after you’ve been in the same position for too long, also known as pins and needles. But there are a number of other causes for tingling in legs that you may not be aware of, especially if you are experiencing the feeling on a regular basis. So what is tingling in legs a symptom of?
Tingling in the legs is a sure sign of poor blood circulation but the root causes of this can vary from lack of exercise to more serious cojditions. Some of these causes include:
If you only experience this tingly uncomfortable feeling in legs occasionally, it might only be due to the way you are sitting.
However, frequent episodes of a tingly uncomfortable feeling in legs and feet can be the result of many common causes, like poor circulation. Some causes of tingling in legs are benign, and some can be more sinister in nature. Let’s dive into the causes of tingling in the legs.
When you sit for a long time, especially with your legs crossed, you put pressure on your nerves and blood vessels, which can limit blood flow and cause tingling in lower legs and even a numb feeling in legs. The nerves and blood vessels can also become compressed, leading to further discomfort.
To alleviate this, you can try standing up and moving around every 30 minutes or so, or adjusting your sitting position to relieve pressure on your legs. Stretching and doing light exercises, such as walking or biking, can also improve blood flow and prevent tingling sensations. If the tingling persists or becomes severe, you should consult a healthcare professional for further evaluation.
People who suffer from anxiety can have some symptoms that vary wildly in frequency, duration, and severity. But many people experience tingling, numbness, or pain in the extremities as a result of chronic anxiety or stress that can worsen when trying to go to sleep or during a panic attack.
Anxiety triggers the body’s “fight or flight” response, which prepares the body to respond to perceived danger. This response can cause a variety of physical symptoms, including tingling or numbness in the extremities, such as the legs.
The tingling sensation is usually a result of hyperventilation, which can occur during an anxiety attack. Hyperventilation leads to a decrease in carbon dioxide levels in the blood, which can cause changes in the pH balance of the blood and lead to tingling or numbness.
Diabetes is the perfect example of how systemic disease can cause a tingling feeling in the legs. Many people with lifelong diabetes or uncontrolled adult-onset diabetes suffer a complication known as diabetic neuropathy, which typically starts with a weird sensation in legs and feet, and can progress to the arms and hands.
Diabetic neuropathy is the result of nerve damage that is caused by chronically high blood sugar levels and can have other symptoms such as a burning sensation, feeling of numbness, and pain in the affected limbs.
Another common condition that can lead to tingling in legs is the restless leg syndrome. Characterized by an irresistible urge to move legs, this neurological disorder is often accompanied by uncomfortable sensations in legs such as tingling, itching, and discomfort at rest.
Since restless leg syndrome can originate from a variety of reasons such as iron deficiency, chronic disease, or even certain medication, it’s important to consult a healthcare professional for a proper evaluation and diagnosis.
Caused by damage or pressure on the sciatic nerve, the tingling, pain, or numbness sciatica can cause usually starts in the buttocks of the affected leg and travels down the leg to the ankle and sometimes into the foot. It usually only affects one leg at a time and is generally treated with anti-inflammatory medications and physical therapy. If you are experiencing one leg numbness, sciatica is a likely cause.
Many vitamin deficiencies can cause tingling in lower legs and the extremities. A Vitamin B12, or cyanocobalamin, deficiency is the most notable of these and can lead to pernicious anemia, which can cause peripheral neuropathy. Other vitamin deficiencies that can cause tingling and similar symptoms in the extremities include:
An electrolyte imbalance can also cause a leg tingling sensation. Potassium, calcium, magnesium, and sodium are the four main electrolytes that carry an electrical charge and help regulate nerve impulses. When they are out of balance, this can lead to the irregular firing of the nerves and the sensation of numbness or tingling in lower legs and the extremities.
Many infectious diseases can cause damage to the nerves in the body resulting in severe complications and symptoms such as numbing feelings in the leg. Some of these infections include:
The herpes virus is the most notorious of the above infectious conditions, especially when it comes to nerve damage, which is typically found in the nerves of the face, ears, eyes, and extremities. Symptoms can range from mild discomfort to excruciating pain and can last for months or years after an active infection.
Vein diseases like deep vein thrombosis or DVT, and even varicose veins, can also cause this tingly, uncomfortable feeling in legs. This is because venous disease disrupts the normal flow of blood throughout the body and can lead to blood clots, which can cut off the blood supply to nerves.
For example, deep vein thrombosis is a blood clot that forms in the deep veins of the leg. DVT can be large enough to put pressure on surrounding nerves, or cut off blood supply to the nerves causing tingling in legs, numbness, and even sharp pain.
DVT can be a dangerous condition if left untreated. A piece of the clot can break away and travel to the lungs leading to a pulmonary embolism, which can be deadly. Call your doctor immediately if you notice any of the following symptoms:
