I have long standing hyponatremia, low chloride plus high TSH 12.8. I have been hospitalized mult times had seizure. Taking 10 1gr sodium. Fluid res?

FInd out why. I trust you are not taking a diuretic for some reason, and i trust you do not have inappropriate ADH (vasopressin) secretion due to porphyria or some other illness. Especially, i hope you don't have undiagnosed addison's disease especially with the high TSH (possible schmidt's). Have you been evaluated for one of the syndromes of renal sodium wasting?
