Hi! I am a 18-year university student.I have a very rare type problem-bad smell from my nose.It was just started this July 2012 and I really don't know how it exist. At first, I thought it was just a bad breath from the mouth that's why I tried to use mouthwash and mouth spray but there was no improvement.Actually it gets worse this August and I can really smell it specially in a close area,in a jeep or even when I'm walking in our campus.I already asked my family and friends and their answers were just the same.They said I have no bad smell from my nose and it is very impossible.I really don't know if they were being true to me or they just don't want to offend me.When I started to smell it I also started to isolate myself, cry every night,and I planned to stop this 2nd semester because it really affects my performances and grades in school,but I failed to do that.Now, I'm having my duty in hospitals,trying to ignore all the embarrassment and every time I'm in a ward I'm spreading this very unpleasant smell.it was so difficult for me to contact or talk to my classmate,CI,and other people in that place specially to our patients.
I had 4 check ups and I already went to ENT. According to them I'm suffering from sinusitis.prescription are just the same-nasal spray,antibiotic,anti histamine and multivitamins but still there's no changes or improvement.lastly I also have a slight left abdominal pain.
Please help me.. I really want to cure this.. thank you very much!
