Hi, I am sorry for the accident you had. The trauma you got from being hit by cricket ball has caused injury including of the internal muscles. It is good that X-ray did not show any sign for bone fracture; however, during the hit, the ball might have injured the external and internal muscles including putting pressure on your lungs and pleura. This is a temporary situation and will improve within a few days. I advise to: - take OTC pain killers - try to eat often and small portions - avoid laying on the left side where you were hit If the breathing won t improve or will get worse in a few days, should go to ER and consult pulmonologist as soon as possible for further evaluations and specific treatment. Wish fast recovery! Dr.Albana
