Some people suffer from "Restless Leg Syndrome" a condition that makes it hard to relax or sleep because the muscles of the legs won't stay still. This would not be a muscular dystrophy which is good news because restless leg syndrome is somewhat treatable. If you could give a few more details of your symptoms that would help. Muscular dystrophy is a long term, progressive illness that gets worse over many years. Good luck to you.
