I have had severe stomach pain almost like a burning on and off for the past few days but tonight it's extremely uncomfortable and not easing up. I have also had frequent urination, black tarry stool, and fatigue.
Yes. A stool that is colored black could mean there is blood in it. The symptoms you describe could mean you have an ulcer or other related concern. It would be best to have a doctor follow up with this as soon as possible. Also think back as to when this started and if anything occurred then that could have triggered this concern as it could help the doctor determine diagnosis and follow up.
