If Your Legs Cramp at Night, You Need to Know This Immediately

Nighttime leg cramps—also known as nocturnal leg cramps—are sudden, involuntary muscle contractions that usually occur in the calves, thighs, or feet while you are resting. These painful spasms can last from a few seconds to several minutes and often leave lingering soreness afterward. While many people dismiss them as harmless, frequent night cramps may be your body’s way of signaling an underlying issue that requires attention.
