I have the same problem, and I also realised from my pictures I have a huge dent in my nose, making it point in one way. But is not noticeable to ppl and to me to until I saw my picture and thought OMG!
You need to see an ENT specialist and get a REAL PROPER NOSE EXAMINATION DONE, which involves puting a tube camera in your nostrils and pushed up.
A little light up the nose check will not do. I went to one ENT before and that is what he did, which was pathetic.
I think a new revolution should take place in the West and MASS CRITICISM AND PRESSURE SHOULD BE APPLIED TO doctors etc. It is unbelievable how many lack knowledge, I have encountered from an endocrinologist, a urologist, a gp and a ENT specialist.
All they see is money and cheap ways to cure peope. No medicine will cure you most likely, if you have been like this for a long time.
I bet by now you are coughing? This is because your forced to breathe in by the mouth rather than the blocked nose, causing, coughs, nose leakages etc I preaume. Do the breathing exercises and see a real ENT specialists.
