My abdomen hurts. Sharp pain on the upper middle left. It hurts on the inside and touching it on the outside hurts it on the inside. When I stand, it hurts to stand straight unless I move more gradually than normal and I feel like I have to walk kind of gingerly not to jar it. It jars and hurts on the inside when I go down stairs. Although the pain is localized, I feel very bloated across all of my abdomen. I do not want to eat. I do not think I have a fever. I thought it was gas yesterday when it started like a sharp, trapped gas bubble, but it has not gone away and hurts a bad as it did, if not worse, than when it started.
