I understand your concern regarding this and it is good that initial diagnostic tests were normal. The exact causes of high blood pressure are not known, but several factors and conditions such as smoking, overweight or obese, lack of physical activity, too much salt in the diet, and even stress and family history may be contributory factors. If the underlying cause cannot be determined, this type of high blood pressure is called essential hypertension. While kidney diseases may be a secondary cause of hypertension, it is best that you check with your nephrologist also to evaluate your kidney stones especially if has been chronic. Take care and do keep us posted.
I saw him this week. He is looking for a tumor in my adrenal gland. It has a very long name I can't think of.
