Just about everyone has muscle cramps at one time or another. And they become more common as we age. They may happen after physical exertion (especially if more intense or longer than usual). But no one knows why some people who exercise regularly are more likely to get muscle cramps while others are not.
In fact, the cause of most muscle cramps is unknown. Risk factors include advanced age, pes planus (flat feet), lack of exercise, dehydration and diabetes. But plenty of people with these factors do not have muscle cramps. And most people with muscle cramps have none of these factors.
Many doctors order blood tests to check your potassium, calcium and magnesium levels. But for most people with muscle cramps, these test results are normal.
That said, there are recognized causes of severe or frequent muscle cramps. They include:
Your treatment would depend on the cause -- if one can be found. So talk to your doctor. He or she may suggest that you see a neurologist, a specialist in nerve and muscle function.
In the meantime, these tips can help:
Many people with muscle cramps (especially those that happen at night) say that quinine helps. But the best clinical studies question its usefulness. Quinine is no longer available in pill form in the U.S., but you can still find it in tonic water.
Muscle cramps are rarely dangerous. But they can be quite painful, aggravating and unpredictable. So its worth trying to find the cause and a safe treatment to stop them.
