How do you prevent severe muscle cramping in legs? Magnesium levels are normal but still taking supplement daily. Cramping begins in feet and continues up into groin sometimes the muscles in shins and calves remain cramped for two or more days. The best way to describe them are severe "Charlie Horses"
These symptoms can be due to different causes and should be evaluated by your doctor. With MS, particularly with spinal cord lesions, the muscle relaxing stimulus from the spinal cord is disrupted which leads to muscle spasticity in the legs which can produce charlie horses. In this case, good stretching of the legs can be quite helpful. There are also anti-spasmodic medications that can help in more severe cases which can include baclofen, tizanidine, and in cases where the cramping is worse at night, low dose clonazepam. While magnesium can lead to muscle irritability when low, this is not the most common cause of these symptoms in MS patients.
