Frequent foot cramps may be caused by physiological factors, but also by pathological factors, such as low blood calcium concentration, thrombotic disease, diabetes, etc. Different causes of different treatments, including general treatment, physical therapy, drug therapy and so on. 1. Physiological factors: Cramps often occur in the middle of the night after sleep, cold, or during long hours of running and swimming, due to the accumulation of lactic acid and carbon dioxide leading to muscle spasms, which is a normal phenomenon. For cramps caused by physiological factors, pay attention to calcium intake, avoid strenuous and prolonged exercise and catching cold. 2. Decrease in blood calcium concentration: Insufficient calcium intake, hypoparathyroidism caused by a decrease in blood calcium concentration can also cause cramps, the mechanism is due to the decrease in blood calcium leading to increased neuromuscular excitability, after diagnosis by a professional doctor to use calcium drugs can be relieved. 3. Thrombosis and diabetes mellitus: Due to the occlusion of blood vessels in the lower limbs, blood supply is insufficient, which may also cause foot cramps. Patients with a history of foot cramps need to check the blood vessels of the lower limbs and do electromyography to clarify the cause of the problem. After diagnosis by a professional doctor, if a thrombus is detected, anticoagulant treatment should be carried out in time. The use of physical therapy such as aerosol and alternating hot and cold compresses can relieve muscle pain, promote muscle relaxation and improve muscle blood supply. In addition, pregnancy, improper sleeping position and high blood pressure may cause foot cramps. If cramps occur frequently over a long period of time, and the symptoms do not improve significantly after taking calcium supplements, you should consult a doctor for a clear diagnosis and symptomatic treatment. The use of medication should be in accordance with medical advice.
