MD Podiatrist Discusses Causes of Muscle Cramps

According to podiatrist Daniel Michaels, DPM, “A muscle cramp is a strong, painful contraction or tightening of a muscle that comes on suddenly and lasts from a few seconds to several minutes. It often occurs in the legs and toes. A muscle cramp is also called a Charley horse. Nighttime leg cramps are usually sudden spasms, or tightening, of muscles in the calf. The muscle cramps can sometimes happen in the thigh or foot. They often occur just as you are falling asleep or waking up.”
  
“If you haven’t strained a muscle, you’re probably cramping because your muscle is fatigued or overused, or your body is dehydrated. Or maybe you’re not getting enough electrolytes, such as potassium or magnesium. These minerals help your muscles work more smoothly, and fluids help your body process the minerals. Most cases of muscle cramps don’t indicate a worrisome underlying condition. People who are 65 and older are at greater risk for them. Cramps may be related to alcoholism, hypothyroidism, or diabetes,” says Michaels.
