I had a terrible case of diarrhea, and ended up having all kinds of blood work, and going on the BRAT diet..and am now scheduled for a colonoscopy. Since that has stopped, I have severe tremors (which I had slight one's before), now it looks like parkinsons now....my legs and other part of my body are weak, I'm off balance, bumping into walls, I'm confused....any idea why these symptoms are happening to me?
