Nostril issue - #9848

I feel something stuck in my either of Nostril On the use of saline it gets resolved 80-90% but it come back after 6-8 hours Facing this from one month It doesn't developed gradually it just came suddenly when i was lying on my bed one day it just came in 3-4 seconds like before that i never felt any problem related to my nose in my life but just after those few 4 seconds this issue started having no other symptom Also i have doubt that it may have a connection with fast breathing exercise which i did very fast When i went to my physical doctor he checked my nose through torch and said that my inner bone is diverted maybe but Even though i have DNS it can not be a sole reason for my problem because since my child hood i never had any problem related to nose due to god grace. And i know that dns can be developed gradually even though In my case it didn't devloped gradually It happened in 3-4 seconds like before those seconds i didn't have any problem But after 4 seconds when i was lying on my bed it started very suddenly there for dont you think it can be due to my fast breathing exercise which i did very fast i literally inhale and exhale 3 times in a second it was that much fast so therefor my concern is that even if i have dns it is not a sole reason/factor for my problem i may have inner injury due to fast breathing or something please diagnose it
