question: I have been having pain on under my right abdominal and back for about the past week now It hurts to walk, lay down, cough, breathe (sharp apin when I tke a deep breath).... almost anything I do I went to the ER a day ago where I was given an untrasound and an xray which both were normal They then did some blood work and the result came back positive The doctor thought that I had a blood clot in my lung so I got a CAT scan which came out normal I was then discharged and given some motrin and narcos for the pain which neither of them seem to help The pain is agonizing. What could it be?
