Accurate. Sometimes it feels like my muscles are pulling away from my bones, too, and it's kind of horrific. This is one way to explain how it feels. It's the most pain I've eve experienced so I have nothing else to compare it to.
Don't Judge: think about how you'd handle having the worst stomach bug every single day of your life! Then add in an erratic heart rates/blood pressures and fainting. Oh, and seizures... I could go on, but I think you get the idea ;)
