I woke up this morning with Mild discomfort in my lower abdomen, the discomfort continued all day I had several loose bowel movements but no diarrhea. After lunch and then dinner the pain increased but subsided after going to the bathroom, more very loose stool. This evening I noticed that when I press lightly on the lower left side of my abdomen it is tender. I have no nausea, don t feel bloated, my appetite is normal, intensity of pain comes and goes, but the tenderness and discomfort on the left side are constant. Any idea s?
