Leg cramps are mainly caused by calcium deficiency, or adverse physical and chemical factors, inflammatory stimuli, neuromuscular abnormalities, etc. Calcium deficiency tends to cause muscle spasms and leg cramps. The symptoms appear mainly in the evening, when the body’s calcium is at its lowest level, and during the day when overexertion or cold in the legs can also easily lead to leg cramps. Leg cramps all the time indicate that the cause of the cramp persists and is not eliminated, mainly seen in inflammation of the joints of the lower limbs, where the inflammation is not controlled and continues to stimulate the muscles thus producing muscle dysfunction. Then there is a herniated lumbar disc that compresses the sciatic nerve causing cramps in the legs and feet, and if the compression symptoms are not relieved, they will remain in a crampy state. So while supplementing calcium you also need to eliminate other factors, choose drugs that soothe tendons and blood, reduce swelling and pain, such as lumbar pain Ning capsules, Panax notoginseng tablets, you can use hot towels to warm up the cramping area to relieve muscle spasms and cramps, and also pay attention to the leg to prevent cold and keep warm.
