Restless Legs

What do restless legs feel like?

Having restless legs means an uncontrollable urge to move your legs, usually when you’re relaxing. An uncomfortable sensation brings on the urge like itching, crawling, or pulling. Moving the legs relieves the sensation. 

Restless legs are a symptom of restless legs syndrome (RLS), a neurological and sleep disorder. 

Why do I have restless legs?

Researchers are still investigating what causes restless legs. They theorize that the unwanted movements may occur because of a decrease in dopamine levels in the part of the brain that controls movement. 

You’re at greater risk of having restless legs syndrome if one of your parents has it. Iron deficiency, use of certain medications (antihistamines and antidepressants), and underlying health conditions like diabetes, neuropathy, and vascular problems can also increase your risk. 

What is the connection between poor leg circulation and restless legs?

Though more of a neurological disorder, people with RLS are at greater risk of cardiovascular disease. The connection between restless legs and leg circulation isn’t fully understood. 

However, researchers believe that the sleep disturbance, constant leg movement, and high blood pressure that occur with RLS negatively affect cardiovascular health, increasing the risk of health problems.

Restless legs are also a common symptom of leg circulation problems like peripheral artery disease (PAD), chronic venous insufficiency (CVI), and varicose veins. 

When should I see an expert about my restless legs?

You should schedule a consultation at Northwest Houston Heart Center if you have restless legs. 

The cardiology clinic offers free vein screenings and vascular exams. Restless legs are a symptom of vascular problems, and an evaluation can confirm or rule out a more serious health condition. 

The specialists evaluate your legs and look for signs of vascular disease, such as poor hair or toenail growth, slow-healing wounds, or swollen legs. You may need additional tests, such as a vascular ultrasound, to confirm or rule out a vascular disease.

Restless legs affect more than your sleep; they may also affect heart and blood vessel health. A free screening at the cardiology center may prevent future health problems.
