What Causes Bruised Feeling In The Throat And Small Patches All Over The Body?

My throat feels bruised , my body has little patches of what seems to be a bruise because it s tender all over my body , I m nauseous ,(dizzy and sick), my whole body is numb, my eyes burn having them open even after a 5 hour nap, when I get in warm water I start to pass out, not throwing up anymore , but it s pretty hard for me to walk, and I got this with my sleeping schedule being atleast 9-10 hours of sleep, and eating pretty healthy, and having water. Oh and chills like I get chills with out even needing a fever to follow after it, and the second I realize I m hot I go back to shivers within five minutes. Been fevering too.
