Hello, I was diagnosed with Restless Leg Syndrome, because I feel the urge in my legs to move and stretch them almost all the time. Because the stretching is actually helping, I want to ask if device like Night Splint which will hold my leg at 90 degrees and apply light stretch all night can help me with RLS?
