I'm not sure if this is another symptom of my RLS, but I find it impossible to sit in a chair and keep my feet flat on the floor. Or sit on the couch with my legs straight on the foot rest. I find I always have to sit cross-legged. And since I'm sitting almost all day long at work, all that cross-leg time hurts my knees. Does anyone else have this "symptom?" If so, what do you do about it?
