Well, this is interesting, Frank. I assumed my hubby's night time spazzy legs were due to his neurological damage. Looks like it could be due to venous insufficiency-
A recent study of the occurrence of Restless Legs Syndrome (RLS) in patients evaluated in a phlebology practice, suggests that RLS appears to be a clinical syndrome that commonly overlaps in patients with venous insufficiency and chronic venous disorder (CVD).
And I'm no longer shy in saying- I think chronic venous disorder of the jugular and azygous veins is implicated in MS...
