Muscle cramps are very common, particularly in pregnant women and older people.
These contractions are always involuntary, do not loosen immediately and cause a visible or palpable stiffening of the muscle lasting from a few seconds to 15 minutes and sometimes longer. They are triggered by an electrical impulse from the body. Frequently, these cramps will occur several times before stopping by themselves .
They can affect any muscle, be it the calves, the legs, the feet, the neck… A muscle contraction can involve part of a muscle, a whole muscle or even several muscles at the same time.
