What can help?
Regular calf stretching—particularly before bed—may reduce the frequency of cramps for some people. During a cramp, gently stretching and massaging the affected muscle can help. nhs.uk
If cramps regularly disturb your sleep, last more than 10 minutes, or occur with numbness or leg swelling, talk with a healthcare professional. nhs.uk
Important: Sudden swelling and pain in one leg, especially with chest pain or shortness of breath, is different from an ordinary muscle cramp and requires urgent medical assessment because it can indicate a blood clot. nhs.uk
