What Causes Abdominal Pain And Nausea?

Hello. In the last several hours my stomach has been hurting, which is progressively getting worse. It hurts to move from one position to another. It hurts to eat, which I end up having to go use the bathroom to have any kind of relief. It almost feels like pulled muscles, but worse, even though I have not done anything to cause pulled muscles. I also feel very nauseous. It is the entire abdominal area. I tried pressing somewhat which was very uncomfortable. Any ideas on what may be causing me to feel like this? Thank you for your time.
