Other people may experience severe symptoms daily. PLMS is characterized by involuntary jerking or bending leg movements during sleep that typically occur every 10 to 60 seconds. Some people may experience hundreds of such movements per night, which can wake them, disturb their sleep, and awaken bed partners. People who have RLS and PLMS have trouble both falling asleep and staying asleep and may experience extreme sleepiness during the day. As a result of problems both in sleeping and while awake, people with RLS may have difficulties with their job, social life, and recreational activities.
Some women experience RLS during pregnancy, especially in the last months.
The symptoms usually disappear after delivery. Low iron levels or anemia. The symptoms may improve once the iron level or anemia is corrected. Decreasing caffeine consumption may improve symptoms. RLS occurs in both sexes.
