When cramps deserve medical attention
Occasional cramps usually aren’t concerning. Talk to a healthcare professional if they happen frequently, regularly disrupt your sleep, or occur with muscle weakness, numbness, swelling, redness, or persistent pain.

Important: A nighttime leg cramp by itself does not mean you have kidney disease, poor circulation, or an electrolyte deficiency.
For prevention, gentle calf stretching before bed, regular physical activity and adequate hydration can help some people.
