The primary cause of restless legs syndrome that produces bouts of anxiety is unknown, but research suggests that nervous system problems related to the brain and spinal cord can cause an onset of the condition, explains the University of Maryland Medical Center. People who are 40 or younger are more likely to inherit the disorder.
Individuals with restless legs syndrome and anxiety experience uncomfortable sensations that are primarily targeted in the legs but may also affect the arms and other parts of the body, according to WebMD. The sensations cause patients to move their legs for relief from an itchy feeling that is often described as a pins and needles sensation. The severity of the condition worsens at night when sitting or lying down. People may experience anxiety accompanied by restless legs syndrome due to interruptions that lead to a lack of restful sleep.
Restless legs syndrome may occur temporarily when people are suffering from chronic long-term health conditions or have become pregnant, explains the University of Maryland Medical Center. Treatment for the disorder involves lifestyle changes that address overall health, diet, exercise and iron supplements. Some physicians prescribe medications to relieve symptoms of both anxiety and restless legs syndrome.
