I was recently punched in the nose and now my nose looks crooked? (Photos)

You should see an Ear Nose and Throat, or rhinoplasty surgeon to be assessed. It is important to make sure there is not a hematoma or collection of blood next to the septum. Also if you desire to straighten the nose, you have a narrow window of time available.

In order to know definitively if a fracture is present, you should seek consultation from a plastic surgeon.  Imaging studies as well as clinical evaluation will help to make that determination.  Once that information is obtained, your surgeon can advise you on how to manage the situation.

Sorry to hear about your injury..Without in person exam- X-ray- it's difficult to comment accurately. Best to be seen in person....

allow swelling to subside over 4-6 weeks.  If you still see an asymmetry, consult a plastic surgeon 

You should see an experienced rhinoplasty surgeon who examines you in person. Ideally, the internal nasal cavities are also examined with nasal endoscopy to assess whether or not you sustained internal nasal injuries. Most Facial Plastic Surgeons perform nasal endoscopies, as do some general Plastic Surgeons. Please see someone sooner than later as a septal hematoma, if present, needs to be drained urgently as it can lead to septal cartilage resorption if unrecognized and untreated, which can ultimately need to a saddle nose deformity. With all that said, you may have the option of a closed reduction (often does not work, though) versus a septorhinoplasty operation. Best wishes!
