Muscle cramps in the backs of your legs, calves, toes, and arches of your feet can cause stabbing pain. These muscle cramps may indicate deficiencies in calcium, potassium, and magnesium. If you experience these cramps frequently, that is an even stronger indicator that a dietary deficiency is to blame.*
You can ease these specific muscle cramps by eating more mineral-rich foods such as broccoli, Bok choy, and dark leafy greens such as kale and spinach. Bananas, squash, cherries, almonds, grapefruits, and hazelnuts may also reduce the frequency of these specific muscle cramps.
