Im craving for salt and my legs get hot at night, i have low cortisol level n have been on medication for nine months why?

Salt craving: Your salt craving is natural for cortisol deficiency. Cortisol replacement is essential and it must be adequate. The med used has to have salt retaining actions. Some require a second med, such as fludrocortisone. Rediscuss with your doc the adequacy of your med. Ask for blood testing to check sodium and potassium levels. Hot legs require doc evaluation too. Suggests nerve problem.
