He had no pain doing deep breath, X ray showed no fracture on rib and spine . What could hurt his stomuch? is it possible there is bruise on his stomach cuase by hard falling? How to help recovering ? thanks [/INST] Hello, Consult a physician and get evaluated. You have to get an X-ray chest to rule out possible rib fracture as it can present with similar symptoms. As of now you can use analgesics/anti inflammatory combination like aceclofenac/seratiopeptdase for symptomatic relief. Hope I have answered your query. Let me know if I can assist you further.
