Cramping is painful due to the cause of unconscious muscle contraction. It is mainly caused by low temperature, exercise after diet, insufficient warm up exercise or excessive loss of body fluid and salt following sweating, vomit or diarrhea. There are different ways of handling cramping at different locations:
For example: When there are cramps at thigh, try to straighten small leg and thigh;
When there are cramps at small leg, point your foot towards your knee;
When there are cramps at foot bottom, straighten your toes.
To prevent cramping, please make sure doing enough warm up exercises before strenuous exercises. Drink water to replenish its loss during exercise. The elderly should wear more clothes at night to keep hands and legs warm.
