MIgraine and leg numbness?

[JPC125]

I wasn't sure what category to post in...I am 30 years old in good health, with occasional migraines for years (usually 2 times a year.)  In the past month, I've had 4, but have been treating seasonal allergies and have not had one in about 3 weeks.  Over the past few days, I've noticed that when I lay down, within a few minutes my legs begin to feel numb, as if they're falling asleep. It starts at my feet and gradually spreads upward.  When i stand up it goes away, and when it's nighttime, if I ignore it i fall asleep and feel fine in the morning.  I don't know if there's any link between the numbness and the migraines, but I thought I'd give it a shot.  because of the heaaches, I had a CT scan of my head and sinuses last week and everything was fine.
