The choice is based on the accompanying symptoms. Generally speaking, if the patient is suffering from hand, foot and facial cramps, numbness and tingling around the mouth and lips, he/she should promptly visit an endocrinologist; if the patient is suffering from dizziness, headache and raised blood pressure, he/she may visit a neurologist; if the foot cramps occur during pregnancy in a pregnant woman, he/she may visit a gynaecologist.
