Hi thanks for contacting a health care magic. Here according to history it seems to be musculoskeletal pain .... It could be costochondritis also if ribs tender to touch ..... Here first take ibuprofen for week... Hot pad can be applied.... Avoid movement that cause pain.... Strenous work not done. Heavy weight lift restricted.... Proper sleep posture.... If needed physiotherapy might helpful.... Compression bandage also helpful. If pain still there myositis or muscle tear has to be rule out.. If pain radiating then better to investigate with echo or ecg for rule out cardiac cause. Take care.
