My son in law is a vascular surgeon and has told me many of his patients with venous disease suffer from RLS. Treat the disease and the RLS disappears. Venous disease is not always apparent (it's not just unsightly varicose veins) and can only be diagnosed by an ultrasound of the legs. People can have it for years without being aware. I am sure that for the majority of us this won't apply but if it can help just one person it may be worth investigating and ruling out?
See the report above.
