Everytime i get a new symptom or feel different i think something else is going on. My right arm and leg feel odd and different to my right. I keep shaking my arm because it feels strange and i can't sit still because then i freak out at how odd my head feels. My breathing feels shallow and keep thinking if i don't remember to breathe that i won't. My back aches off and it feels like there is a brick in the middle of my back. Keep waking up sweating and odd feelings and sensations.
