Restless legs syndrome (RLS)
Overview:
Restless legs syndrome (RLS) is a condition characterized by a strong urge to move the legs which is difficult to resist. This need for movement is often accompanied by uncomfortable sensations that are difficult to describe, but may be like burning, prickling, itching, or tingling. Symptoms begin or worsen while resting, and lying down or sitting can be uncomfortable. Temporary relief occurs when legs are moved.
Symptoms:
- A strong urge to move your legs, often accompanied by uncomfortable sensations
- Symptoms begin or worsen while resting
- Symptoms improve when legs are moved
- Symptoms worsen in the evening, especially when lying down
- RLS can also cause difficulty in falling or staying asleep
Tests and diagnosis:
In order to diagnose RLS, a doctor may recommend:
- A polysomnogram (sleep study)
- A blood test
Treating restless legs syndrome:
While RLS cannot be cured, it can be managed. In some cases, doctors will prescribe medications that help control the painful sensations and impulsive movements. Those with mild cases may benefit from changes in lifestyle such as avoiding caffeine, practicing good sleep principles, and massaging the legs.
