Can you break your nose with little to no pain? It is only slightly crooked, but it barely hurts.

Dear gsalas24,it is hard to tell for sure without an examination. In most cases, nose fracture is followed by immediate pain, swelling, bleeding.  I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Its possible that you featured your nose.  Typically there would be pain, swelling and bleeding.  In order to assess your injury you need to be seen by a nasal surgeon. Their assessment will include an exam of your external and internal nasal anatomy. 

You should come in for an evaluation within 5-7 days after the injury so we can see it after the swelling has subsided. If it looks crooked and bones are still mobile, we can reposition it. Best wishes

Generally speaking, broken nasal bones are tender to the touch. Sometimes the bones are broken but still in the correct position. As long as the bones are covered or protected, they will heal fine. If your nose already looks crooked, there is a strong possibility that your bones are broken and it is best to have the bones reset back into the right position. It is best to have an evaluation immediately. Imaging studies such as x-rays or a CT scan can determine if and where the bones are broken. If you wait too long (over 2 weeks), then the bones will have started to heal in their position and if you need correction, your surgeon may have to rebreak the bones to fix them.

 Trauma to the nose can cause a displaced nasal fracture, non-displaced nasal fracture, a dislocation of the upper lateral cartilage off of the nasal bones, and a fracture of the septum, also known as a deviated septum. Each one of these issues are treated differently. X-rays and a thorough internal and external examination the nose will be required to document the extent of the injury. Make an appointment with a double board certified ENT/facial plastic surgeon who can address both functional and cosmetic nasal surgery

I would suggest you find a plastic surgeon certified by the American
Board of Plastic Surgery and ideally a member of the American Society for
Aesthetic Plastic Surgery (ASAPS) or facial plastic surgeon
(otolaryngologist) that you trust and are comfortable with. You should
discuss your concerns with that surgeon in person.

Thank you for the question and sorry for your concerns.  That said see a specialist and get examined rather then worryDr Corbin

I suggest you consult with a nasal specialist for evaluation after the nasal trauma. Treatment of a nasal fracture which may cause little pain depending on your pain thresold iis not always necessary unless there is a change in appearance or function. Your appearance today may just be secondary to temporary swelling that will resolve.
