If you even SUSPECT MS, have your GP test your potassium regularly!! I had a sudden cardiac arrest in the neuros office due to severely low potassium(ironically for my official MS diagnosis). I was misdiagnosed for almost a decade & it literally killed me...please take the warning seriously!! I agree with the rest of your post...a friend of ours, his nephew has "social anxiety"& gets SSDI...but volunteers with his church, works part time, all just fine 🙄 he just doesnt want to grow up & get a real job, so SocSec to the rescue-makes me sick!!
