Sleep leg cramps: 25 F I wake up frequently with Charley horse, arch cramps, and even cramps that make my ankle go stiff. I take vit d and magnesium and it helps some.. ANS: need much more detail and I specialize in causes of low blood potassium(K) which is a common cause of this. The cause of the low K must first be found then it can be treated and they will stop. Happy to do 2nd opinion.

Medical checkup: There are multiple potential causes for night time muscle cramping. A good medical checkup with a check of your electrolytes and a good exam is a good place to start.
