Leg cramps are sudden pains in your legs caused by your leg muscles becoming tight.
The main symptom of leg cramps is sudden, severe pain in your leg that lasts for a few seconds or minutes.
Stretching and massaging your leg muscles can help with leg cramps. If this does not work, a GP may suggest other treatments, such as quinine tablets.
Cramps can sometimes be caused by ageing, doing lots of exercise, dehydration and pregnancy.
