welcome to HCM,
Though nighttime leg cramps
are common, But most of the time it is not because of illness. Some of the things that may cause leg cramps include:
-Getting too much exercise or overusing the muscles.
-Standing on concrete for a long time, sitting for a long time, or putting your legs in awkward positions while you sleep.
-Not having enough potassium, calcium, and other minerals in your blood.
-Being dehydrated, which means your body has lost too much fluid.
-Taking certain medicines, such as antipsychotics, birth control pills, diuretics, statins, and steroids
-Having flat feet.
-Having thyroid disease
