Sleeping at night leg cramps can take massage leg muscles, warm water foot soak, calcium supplements and other treatment methods. 1. Massage leg muscles: when cramps occur, you should quickly stretch and massage the spasming muscles, which can relieve the local pain caused by cramps. 2. Soak your feet in warm water: Soaking your feet in warm water can help improve blood circulation in your legs and also relax your leg muscles, thus reducing pain. 3. Calcium supplements: When calcium is lost in the body, it can lead to increased neuromuscular excitability, which may cause muscle spasms or strong contractions. Leg cramps caused by calcium deficiency can be improved by taking oral calcium tablets. If the patient’s leg cramps are more serious and last for a longer period of time, it is recommended to go to the hospital to find out the cause for treatment so as not to delay the condition.
