I have had dull pain that comes and goes below my left rib cage for a little less than a week. Tonight I had pain shoot from my chest to my left rib cage. What could it be? I am a full time CNA that uses my left arm and side to lift my residents constantly all day every day pretty much. I had an ovarian cyst rupture before when I got off of my birth control but I got on birth control pills to prevent more occurring. I’m just getting concerned about what it could be. I can push on it and nothing hurts, I’ve had some pain my pelvic area, and when I tense up my abdominal muscles it slightly hurts at times.
