My nose is ruining my life; what should I do? (Photos)

You have a very narrow nose, especially in the mid vault area, and likely have narrow nasal valves, and possibly valve collapse,  obstructing your breathing. A thorough exam would make the diagnosis but you might benefit from a surgery to open your nasal passages and finally relieve your frustration. Find a good rhinoplasty surgeon who you trust to discuss further. Good luck!

if you cannot breathe through your nose, you  should see an otolaryngologist.. They can make a diagnosis and recommend a plan of treatment, surgical or otherwise.
