The crooked nose
You likely have a deviation of the nasal septum or dislocation of the septum that is causing your nose to deviated to the right side. The nasal obstruction is due to narrowing of the nasal passage inside. With both a cosmetic and functional problem the correction can be very challenging. You would be best treated by a Facial Plastic surgeon or general plastic surgeon who has an otolaryngology background as well. Unfortunately there is not a reliable non-surgical fix to your condition. The procedure required would likely be a septorhinoplasty with cartilage grafting.
