Hi, I am a 19 year-old female. I have been suffering from a pain in my lower left abdomen for almost 3 months. It came suddenly one day and hasn't gone away. I have had CT Scans and Blood Tests, but nothing showed up. Then I started having pressure in my chest about 2 months ago with the side pain. Now, the pain is most severe still in the left side and is constant during the day. But, the pain now spans over my entire abdomen, my lower back, my left shoulder and my heart. Right now, the worse pain is in the heart. I am having trouble taking deep breaths, though I took a test yesterday and my oxygen levels were fine. I have no appetite but I am always hungry. Anytime I eat the pain worsens, even gluten-free foods and lactose free foods. I have lost 10 pounds in the last 2 months. I feel constantly faint and weak. What is going on with me?
