Any time that there is a persistent and significant change in your bowel habits which accompanies persistent pain, it is important to speak with your doctor
about what could be happening. GERD, or gastro esophageal reflux disease, is not likely to explain either the changes in your stool or the abdominal pain
that you have been suffering from. What is more concerning is that you could be having problems with either your liver or your gall bladder, or other parts of your bowels. While there are many potential causes of your symptoms, some of them can be very serious and you should speak with your doctor soon so that he or she can order the appropriate tests and hear more about your history. This would then allow you to be treated appropriately if it is needed, or to at least understand what is happening to you. There are questions that need to be asked about the relation of the pain to eating (before or after), as well as if there is anything that makes it better or worse. Please speak to your primary care doctor
soon to begin the process, and explain your various symptoms and what you have done to relieve them.
