Yes, I have had a metabolic work up, have seen a Nephrologist, have seen my Endocrinologist, yet symptoms persist and they are new to me, never having experienced such before. Sodium levels are always low and my kidneys abnormally hold water. Lowering fluid levels and increasing salt in diet are two strategies suggested as well as a trial in Clodinine and doing a hormonal lab. I have had a heart attack and a TBI from a car accident and an oblated thyroid gland. I am of normal height and weight. The symptom checker does not seem to fit for me.
