Restless Legs Syndrome
The exact cause is not known. Certain genes may be cause or increase the risk RLS. It may also be unmasked or worsened by some medicine, changes in level of iron, and other illnesses.
RLS is more common in women. It is also more common in people over 65 years of age. Other things that may raise the risk are:
- Family history
- Taking certain medicines, such as antidepressants and antihistamines
- Low iron levels—may or may not be caused by anemia
- Chronic kidney disease
RLS can cause:
- An urge to move the legs and symptoms ease with movement
- Feelings of pins and needles, creeping, pulling, prickling, or pain in the legs
- Problems that get worse in evening and night
- A hard time falling asleep and staying asleep
You will be asked about your symptoms and past health. A physical exam will be done. This is often enough to make the diagnosis. There is no test for RLS itself. Tests may be done to look for things triggering RLS. Tests may include:
- Blood tests to check iron levels or kidney changes
- Sleep study to check leg activity and sleep problems
