Is it possible to have a broken nose and not know about it?

Yes, it is possible to have a broken nose and not realize it, especially if the fracture is minor or if there are no severe symptoms like intense pain, swelling, or deformity. Some people may attribute mild discomfort or bruising to other causes, such as a minor injury or allergy. Additionally, adrenaline during an injury can mask pain, leading to a lack of awareness about the severity of the damage. However, if symptoms persist or worsen, it's advisable to seek medical evaluation.
