I have had restless leg syndrome since I was a small child. I must disagree with this statement: All of the above recommendations are good but it must be remembered that RLS is related to a circulatory/vein issue first and foremost. There are many causes of RLS. After years of asking doctors what caused the problem and getting no answers, I finally went to a nutritionist who practiced holistic medicine. I did this because I had identified some things that triggered my leg problems: sitting in an area with a cold draft around my legs (airplane) and foods (caffeine and any type of sugar). The nutritionist required very extensive family and personal medical histories and a recent blood screen. She pointed out that my bad teeth and fingernails were important clues, but the most important fact was in the blood screen. She said that I had abnormally low calcium, magnesium, potassium, phosphorus levels in my blood and that meant that I didnt metabolize those important minerals. She said that I needed to take calcium/magnesium supplements for the rest of my life. So, I went through the first 50 years of my life calcium deprived and sleep deprived. That nutritionist and my current dentist are the only health care providers who have ever recognized restless leg syndrome. My dentist has the same problem and takes calcium/magnesium supplements. He discussed with me the way our digestive systems work. It is divided into sections that metabolize specific nutrients. It is called selective absorption. If the section that is designed to absorb calcium, magnesium, potassium doesnt work properly, you will have health problems associated with deprivation of those minerals. After hip replacement surgery, my restless leg problems were extreme. My orthopedic surgeons PA said, It is not uncommon for hip replacement surgery to damage the sciatic nerve, and sent me to a neurologist, who prescribed gabapentin and physical therapy. Both help me sleep. My experiences demonstrate that RLS can be caused by defective digestion systems and nerve damage.
