I am having really bad abdominal pain that gets severe when I bend over, lift something, or sit down. Yesterday, I was just nausea, and a headache, a little fatigued....today its worse. The pain was so bad, my fiancé had to help me up when I sat on the floor. I have a poor appetite, my urine is very dark yellow. The other day, I had terrible gas and diarrhea, but the pain today brought me to tears; and it is worsening.
