  • Leg feelings make it hard to fall asleep

Restless leg syndrome (RLS) is also called Willis-Ekbom disease. It causes an uncomfortable urge to move the legs, most often in the evening or at night. It is a common cause of insomnia (trouble falling or staying asleep) and broken sleep.

What are the symptoms of RLS?

  • Uncomfortable feelings — Feelings in the legs such as crawling, tingling or aching
  • A strong urge to move — An urge to move the legs that is hard to resist
  • Worse at rest — Symptoms get worse when you rest and in the evening
  • Moving helps — Walking or stretching brings relief
  • Trouble falling asleep — It can be hard to fall asleep

How is RLS diagnosed?

Doctors mainly diagnose RLS by asking about your symptoms. They check them against a set list of signs. You may also need:

  • Iron tests — Low ferritin (the iron your body has stored) is a common cause that can be treated
  • Blood tests — To check how your kidneys work and look for other causes
  • Sleep study — To check for leg movements that repeat during sleep (periodic limb movements)

How is RLS treated?

  • Iron pills — If your ferritin is low
  • Dopaminergic medicines — Medicines that act on dopamine, a brain chemical
  • Alpha-2-delta ligands — Nerve medicines such as gabapentin and pregabalin
  • Lifestyle changes — Regular exercise, and no caffeine or alcohol
  • Better sleep hygiene — Healthy sleep habits
