Muscle cramp can be very painful, typically occurring in your legs or arms. If you’ve ever been for a really long jog, or pushed yourself a bit too hard in the gym, then you have probably felt this uncomfortable muscle spasm, but thankfully the pain doesn’t usually last for very long.
The science behind cramping is poorly understood due to limited research in the area, but the most widely accepted theory is that cramping happens when the muscle becomes over stimulated. Without a chance to relax, the muscle can’t return to its original size, causing the pain we know as cramp.
