Ribs and scapula fissure fracture

I am a 31 years man.I had a hairline(fissure) fracture in the first and second rib of the right chest and also a hairline fracture in the back of the right schoulder due to an attack with sticks 4 years ago.
Recently I felt a pain in the chest ONLY when i was playing a basketball match. I did one view x-ray on the chest and two views on the right schoulder to make sure that everything is fine. Here are the x-ray results:

X-RAY OF THE CHEST AND BILATERAL RIBS:

Views of the bilateral ribs and the chest were obtained.

The study failed to reveal any obvious fracture or dislocation. No pneumothorax or pleural effusions were seen. The cardiac size was normal. The lungs appear to be unremarcable. The mediastinum and the soft tissues were unremarkable.

X-RAY OF THE RIGHT SHOULDER:

Two views of the right shoulder obtained reveal osseous structure without any acute bony findings. The soft tissues and the bony mineralization were normal.

The x-ray did not show any symptoms of a fracture according to the radiologest report. Is that possible for the ribs and shoulder bones to be completely healed within 4 years that it doesn't show any past fracture in the x-ray?

N.B. please reply as soon as possible, because i need your opinion to comfort me as i am afriad of that pain i felt to be something else.
