I ve been having weird pain in my belly, like something inside is stretching and ripping it. It s been going on for a few days with sharp pain, and it comes and goes. Today, every time I inhale a deep breath, or cough, I feel a sharp pain in my stomach. My stool is also tarry. (I ve had my gallbladder out in 2013). Do you know what this could be? Thank you for your help.
