I had this problem in my stomach the other day, the epigastric region, where it felt like its getting squeezed, I had nausea for about 4 days and diarrhea but it did not persisit.. I had also fluctuating fever ranging from 37.6 to 38. Pain is elevated with walking or doing any activity. I went to the ER twice all I got was a paracetamol drip and a bascuban they ordered some blood tests, the 2nd time I had the same drip but they told me to take flagyl for a couple of weeks. I still feel weird but not as much. Now I have this pain in my left illiac region of the abdomen its been elevated since two days sometimes it porceeds to my left lumbar region, I can feel it my back as well, but it goes away its not persistant. What does that mean?? Im 20, a female and Ive got free medical history no chronic disease no previous surgeries no allergies, and I exercise.
