So, what causes leg cramps at night, what can you do when one strikes, and when should you talk to a healthcare professional?
Let’s take a closer look.
## What Are Nighttime Leg Cramps?
A leg cramp is a sudden, involuntary tightening of a muscle. During a nighttime cramp, the muscle contracts unexpectedly while you're sleeping or resting.
The calf is the most common location, but cramps may also affect the muscles of the feet or thighs. The sensation can range from uncomfortable tightening to intense, stabbing pain. After the muscle relaxes, the affected area may remain tender for hours and sometimes longer. nhs.uk+1
Night cramps are different from **restless legs syndrome (RLS)**. RLS usually creates an uncomfortable urge to move the legs and isn't typically characterized by the sudden, intensely painful muscle contraction associated with a cramp. Mayo Clinic
