Talk to Ent Specialist on Nose Block At Night

AOA. Every night when and whatever time I go to sleep I started feeling nose blockage and this makes me very uncomfortable and disturb my sleep and sometimes it makes me so disturb that I wake up in hassle and not able to breath from nostrils and start breathing feom mouth. This also makes me think and or feel k brain ko oxygen properly nahi mil raha jis ki wajah se I feel other issues like anxiety, dizziness and laziness. I also have Vertigo issues, once a year in hot and humid days mai aik baar zaroor hota hai ya jaha oxygen level low feel ho ya bohot crowd ya public ziyada ho, ya suffocated or in closed areas... anxiety start ho jati hai. I visited ENT and he said k nose bone has enlarged ho gayi hai but no surgery required and gave me Nosemet nasal spray and Jardin D tablets to use. Please guide.
