Advice? My lower left front side of my stomach has been hurting for a few days. I thought that it was cuz I had diarrhea, but it is just feeling more tender and I haven't had diarrhea for 3days. Its a constant dull pain unless I take a deep breath or when I touch the area then it hurts way more. Can't get in to see a doctor until after 1:30 this afternoon
