Can my teen speed up recovery from cracked ribs?

Dr Phil Kieran: "I used to work with an emergency medicine consultant who told us not to X-ray a suspected broken rib because if it’s bruised, it’ll hurt for three weeks, but if it's broken, it will still hurt for three weeks. His point was that the treatment would be the same, so we shouldn’t expose the patient to unnecessary X-rays."
Rib injuries can be incredibly painful, and I can’t imagine having this on top of the stress of having to sit State exams. Fortunately for your daughter, she is likely already through the worst of the pain by now and should be more or less pain-free by the time the exams come around.
