I don't think there's a reason NOT to get an x-ray, unless you're severely iatrophobic (fear of doctors). If you get an x-ray, you'll either have A) confirmation it's broken and can get treatment or B) confirmation it's not broken and peace of mind. If you don't get an x-ray it's either A) not broken and no harm done or B) it's broken, continues to hurt and might heal wrong.
