Hi Aisha, I echo the suggestion to see a doctor for proper diagnosis. Leg cramps are common esp at night, and they have many causes. From electrolyte imbalances(low sodium and calcium) to neurological involvement and finally clots in the dep veins of the leg. So it is vital thaat you see a doctor soon. Here is a website that can answer a few of your questions and hopefully put your mind at ease,
