My wife was went to the e.r this morning with sharp pains in her chest when she took a deep breath. She is 24 years old and in good health. All vitals were normal, no coughing or other discomfort. E.r doctor ordered chest x-ray and ekg. All came back normal. They said she has pleurisy, but with no underlying cause. Is this normal, or did they miss something?
