Symptoms:

The disorder consists of sensations in the lower legs that make the person uncomfortable unless the legs are moved. The sensations usually occur shortly after going to bed but may also occur during the daytime.

The abnormal sensations occasionally occur in the upper leg, the feet, or the arms, in addition to the lower leg.

There is an irresistible urge to walk or move the legs to relieve the discomfort, resulting in periodic episodes of leg movements during early sleep stages. Symptoms, which may last for 1 hour or longer, can include:

• Abnormal sensation in the legs (occasionally, feet, thighs, arms)
  • Creeping sensations or discomfort (not pain, not cramps) relieved by movement of the legs
  • May occur during the day
  • Worse when lying down
• Irresistible urge to move the legs
• Persistent leg movements during sleep hours
• Sleeping difficulty

Note: Symptoms may be worse during stress or emotional upset.

Signs and tests:

There is no specific examination for restless leg syndrome. No structural or other abnormalities are usually discovered unless peripheral nerve disease is also present. Blood tests (CBC and serum ferritin) may be done to rule out iron deficiency anemia, which rarely has been associated with restless leg syndrome.

Examination and testing may be used to rule out other disorders that may cause similar symptoms, especially disorders associated with ischemic claudication of the legs.
