Is Requip Recommended For Restless Legs?

I have been using requip for restless legs for 6 or 7 years, I've asked every Dr I have met about it, one sent me to a neurologist, I had a nerve conduction study, sleep study, mri of brain and low back, etc etc etc, Now I have learned that my varicose veins could be the cause. Why didnt a Dr. tell me about the v. veins being a cause?
