There may be possibility of rib fractures ar underlyuin contusion
You must go for chest xray PA view to see any rib fractures, any collection of fluid in the pleural space.
Collection in the pleural space may be blood and needs urgent evacuation or else will lead to infection and fibrosis
In the mean time you may try analgesics...
meet your doctor and take his opinion...
