The first time it happened, it was because I had the shortness of breath, plus my arms went numb. After a blood test, they said my sodium was
low, and the potassium was out of whack (forget if it was high or low). Regardless, they gave me a saline solution IV, and told me it was probably because I had a panic attack (despite being a very calm person). The second time, they again told me my sodium was low, and did the same thing.
Since then, everything has seemed to worsen.
