DEAR DR. ROACH: Why do people snicker when I tell them I have RLS? They wouldn’t laugh if they knew the amount of sleep deprivation I have endured during the 20 years it took to correctly diagnose it. I think if it hadn’t been for Sinemet (levodopa and carbidopa), a Parkinson’s drug, I would have gone mad long ago. Has anyone discovered what causes it? — G.S.G.
ANSWER: Restless leg syndrome causes an urge to move the legs (and sometimes arms), which is worse at nighttime and is relieved by movement. It is usually accompanied by unpleasant sensations in the legs. When accompanied by sleep deprivation, as yours has been, it is also called periodic limb movement disorder.
The cause is known only in a minority of cases. About 40 percent of cases seem to run in families, and several genetic factors have been identified. Iron deficiency sometimes is associated with RLS, and replacement of the iron can improve symptoms. Moderate exercise, leg massage and heat (say, a warm bath before bed) are some nondrug ways of improving symptoms. Levodopa/ carbidopa is an effective treatment ; pramipexole (Mirapex) and ropinirole (Requip) also are effective for many people. An expert in the condition, usually a neurologist, is essential for severe cases.
I think the name “restless leg syndrome” may be part of the reason why people don’t take this condition as seriously as it deserves. For this reason, the new name, Willis-Ekbom disease, is preferred by some.
DEAR DR. ROACH: I am looking into buying an infrared sauna. My research indicates that infrared is good for arthritis, Type 2 diabetes, detox, cholesterol, weight loss, relieving muscle pain, helping kill cancer cells, etc. I have arthritis, and my boyfriend has diabetes.
My question is: Are these claims true?
ANSWER: An infrared sauna uses light waves to heat up the body. People have been using traditional saunas for centuries, and many swear by their benefi ts. There is good evidence that saunas (and infrared saunas in particular) can reduce pain and stiffness from some kinds of arthritis. Unfortunately, there isn’t evidence to support it.
I doubt that saunas help with “detox,” weight loss or killing cancer cells. Some people with diabetes are less sensitive to heat and could be burned without knowing it.
