Do I have collapsed nasal valve? If so, where do i go for diagnosis and treatment? (photo)

Dear Kathijkg,I am sorry you are having difficulty with your nose. It sounds like you need to see an ENT specialist ASAP to assess your breathing problems. I would get a second opinion as you should not feel like you are dying. A full exam is necessary to assess if you have a collapsed nasal valve. Best of luck!Best regards,Nima Shemirani

You may have some degree of nasal valve collapse, but it is not possible to complete the diagnosis on the basis of a photo. Regardless, your breathing problems to me sound far more serious than just a nasal valve. I would strongly recommend that you see your internist or cardiologist for a complete assessment of your heart, lungs, circulation and respiratory systems, given the significant degree of your symptoms ( feels like your dying, barely walk and serious hyperventilating ). Please don't put this off. See your physician as soon as possible and tell him/her how you feel with breathlessness and related serious concerns. 

You don't have external nasal valve collapse but you do have soft tissue constriction in the internal nares on your lateral skin per your photo; an examination of your nose with a speculum is needed to determine if you have internal nasal valve collapse.
