Having restless feet at night is caused by restless leg syndrome, but causes of restless leg syndrome, or RLS, are unknown as of 2015. Some factors associated with RLS include chronic diseases, medications and pregnancy, according to WebMD.
Chronic medical conditions such as Parkinson’s disease, kidney failure, diabetes and peripheral neuropathy commonly have symptoms of restless leg syndrome. Treating these conditions may help relieve the symptoms of RLS, explains WebMD. Medications such as antidepressants, allergy medicines, antinausea and antipsychotic drugs have been known to worsen RLS symptoms in some cases. Many pregnant women experience RLS during the last trimester, but these symptoms usually go away within a month after delivery. Alcohol use and sleep deprivation may also trigger RLS symptoms or increase them.
Since the cause of the condition is unknown, treatment for RLS aims at easing symptoms. Regular exercise, establishing a regular sleep schedule and reducing the use of caffeine, alcohol and tobacco may help reduce RLS symptoms in people with mild cases, states WebMD. At-home treatments include massages, hot baths or applying heating pads or ice packs to the legs. Medications used to treat RLS include sedatives, drugs that work on the dopamine neurotransmitter and drugs that treat seizures.
