Ms Hill your complaint seems to be deficiency of some essential nutrient. Calcium deficiency is a common cause of calf pain in your age group. It may be that you are off and on electrolyte deficient too. If you are taking any Blood Pressure medication please refer it in your next correspondence. If you have to urinate more frequently it must be a diuretic . Diuretics are common cause of Electrolyte deficiency. Also if you give your blood for Calcium and Electrolytes, please tell them to check your Vitamin D levels too. I think therapeutic doses of Calcium and Vit D will benefit you. Out of the foods, eat Poultry and drink milk frequently .They both are rich sources of Calcium and Vit D as also is Banana. Hope that helps.
