उत्तर
A muscle cramp is a sudden, spontaneous, sustained and painful contraction of one or more muscles. It is caused by excessively excited nerves that stimulate the muscles. Any muscle group can be affected, but the calf and forefoot muscles are most commonly affected. Muscle cramps often occur after strenuous exercise or due to a reduction in the body’s water and salt content.
