Restless Leg Syndrome

Restless legs syndrome, also known as Willis-Ekbom disease, is a common condition that causes unpleasant, overpowering sensations in the legs that you can only ease with movement.
Symptoms typically begin at night, and can be either chronic or sporadic. RLS can keep you from falling asleep and can often wake you up in the middle of the night.
