When cramps occur in the legs at night, you can take the following plan, use your hand to pull the cramped toes, slowly pull in the direction of the back of the foot, driving the gastrocnemius muscle on the back of the calf, so that the spastic muscle slowly relaxes, usually about 1 minute, the pain will slowly ease after the gastrocnemius muscle relaxes, and the pain will be eliminated. Another method is to use your foot to step on the bed board when you have a cramp to slowly release the spasm in the triceps muscle of your calf. When you sleep, you should pay attention to local warmth. Patients who are particularly fond of cramps can place hot water bags or pay attention to wearing autumn pants and other warmth for sleeping to avoid getting cold again and causing cramps. If you have walked a lot during the day and your legs feel tired, you can soak your feet in hot water at night to relax your muscles and reduce the frequency of cramps.
