hi-
Jen S is right you MAY have RLS. One of the symptoms is:
http://www.mayoclinic.com/health/restless-legs-syndrome/D...
"Nighttime leg twitching. RLS may be associated with another condition called periodic limb movements of sleep (PLMS). Once called myoclonus, PLMS causes you to involuntarily flex and extend your legs while sleeping — without being aware you're doing it. Hundreds of these twitching or kicking movements may occur throughout the night. If you have severe RLS, these involuntary kicking movements may also occur while you're awake. PLMS is common in older adults, even without RLS, and doesn't always disrupt sleep. More than 4 out of 5 people with RLS also experience PLMD. "
One of the causes of RLS is a vitamin/mineral deficiency – typically Iron, folic acid, Vitamin B and/or Magnesium. Do you know if your levels are okay? If they are low you may want to try a supplement (if you find a “food-based” product is should be easy on the stomach).
You may also want to consider a sleep study.
Good luck!
