The following measures can be taken: 1. Keep the muscles of the calf fully relaxed and rested, avoid continued exertion, and try to adopt a passive ankle flexion position, so as to effectively prevent the muscle tissue from becoming tense and twitching again. 2. Keep the calf area warm and do not get cold, as the muscle tissue will become tense after getting cold. The blood circulation will be slowed down and the inflammatory stimulus will increase, which will easily trigger the reappearance of the calf. 3, you can take oral Eperisone Hydrochloride tablets, which are muscle relaxants and can effectively relax the muscle tissue to avoid the reappearance of the cramp. 4, you can go to the hospital for blood tests to see if there is hypocalcemia, if there is, you need to take intravenous calcium and oral calcium supplements. If so, intravenous and oral calcium supplements may be required, or foods with a high calcium content may be added to the diet.
