What’s wrong with leg stomach cramps? Leg stomach cramps reflect several problems: first, calcium deficiency, which causes cramps; second, lumbar disc lesions stimulate the sciatic nerve, which can also cause cramps; third, excessive fatigue can also cause cramps. In short, there are many complex causes. Once cramps appear, you should ask a professional physician for detailed examination, including endocrine examination, imaging examination, ultrasound examination, and laboratory examination, etc., to find out the cause and treat the cause in order to have good results. Patients should not buy or take medication on their own, nor should they treat themselves with acupuncture or massage, but should wait for a clear diagnosis and treat the cause. Whether it is the treatment of chemical drugs, physiotherapy, acupuncture, Chinese medicine or herbal medicine, only when the cause is treated, can we receive good results. If the diagnosis is not clear, the treatment measures will not be effective, and the disease will be easily delayed.
