My blood sodium is 124. I have had body twitching, slurred speech and cannot read as I am seeing double and with blurry vision. I also feel weak and keep falling asleep. I have been to the ER, and to my Doc, who said it twitching continues and seeing double to go to ER and have them admit me, as I can go into seizures. I have multiple autoimmune diseases, and feel so very sick. I have high blood pressure, and vasculitis. I am scared. When should I go back to ER.
