Hi, over the last week I have seen blood with my stool, and through out the course of the day, I have a heavy feeling in my chest, I have pain and discomfort in my lower back which extends around like a belt, my right leg more than the left feels heavy and I feel like I am floating when I am walking. I am also having severe heartburn and most times I eat the food comes up in the back of my throat and sometimes it burns. I feel like I am falling apart!
