This is Dr. David
it sounds like you have restless leg syndrome at night.
you might benefit from medication treatment for restless leg syndrome
medications like sinemet or requip (ropinirole)
these are medications your doctors can prescribe to you.
have you talked to your GP doctor about these leg pains and cramps at night?
you should also get your potassium and magnesium levels checked to see if they are low.
which can also cause cramps at night as well.
