I am experiencing severe pain around my upper left rib area. It hurts to laugh and take deep breaths. I also woke up this morning, strangely, with pink eye and did not relate the two until someone mentioned mono? I also have a nurse friend who said it could be my lungs, yet I don t feel sick. I had an X-ray early last week, and they ruled out a broken rib, and now the pain has gotten much worse. Would the X-Ray have shown an infection of some sort? It was taken about a week ago. Thank you, Gina
