I had a black stool ten days ago. It was not smelly. I am terrified it is cancer. Otherwise I have had normal stools and am currently being assessed for irritable bowel syndrome (IBS).

I have been having lower back pains for the past few days and short of breath sometimes, but I also have been constipated in the same time period, with hemorrhoids, there are sharp pains on the outside of my anal area. It feels like I was trying to push out broken glass at some point and around a teaspoon or more sometimes of blood with some blood clots. I have heard from my doctor in the past that I am anemic and required me to take iron. I'm pretty sure the loss of blood has been making me tired and dizzy while standing too long or standing too fast.
