Hi! I have been back and forth to the restroom today with an unsettled tummy. I had very loose stools and lots of rumbling in my tummy. i have had this burning feeling in the back of my throat all the way down into my tummy, as well. i have had the chills off and on, and now I am very achy in my back, shoulders, wrists, and even the bottom of my feet . Does this sound like a virus or the flu?
