Specific relief measures should be taken according to the cause of the cramps. Causes of knee cramps include overwork, calcium deficiency, etc. Patients can be relieved through massage, hot compresses and calcium supplements. 1. Massage: gently massage the knee, slowly stretching and stretching the muscles at the upper and lower ends of the knee to keep it in a stretched state. 2. Hot compresses: You can use a towel to apply hot compresses to the knee. The warmth of the limbs can promote blood circulation, which in turn transports nutrients and oxygen to the body’s muscle cells and carries away the metabolic wastes produced, thus relieving the cramps. 3. Calcium supplement: you need to properly supplement calcium tablets containing vitamin D, food and more sunshine, but also pay attention to the daily intake of a certain amount of fresh vegetables, fruits and nuts. In short, occasional short-lived knee cramps do not cause serious consequences, but multiple cramps within a short period of time should be promptly sought medical treatment, so as to achieve early detection, early diagnosis and early treatment.
