Hii... for the last few months i feel difficulty in breathing and its like my noses are blocked.. i have identified that my sense of smell is almost gone .. and i feel like i am always having a cold. Runny nose and all.. and yeah snoring. . My parents says i snore like an old granndpa... i am 19 now... one night two sides were blocked and i couldnt breath and felt like....well i was scared to death. . When ever i take a shower or on my AC i feel the same way... and yeah... i have had changes in my vision too .what could this be.?. should i consult a nearby doctor? Is this a serious issue? And what should i do next.? Thank you for taking your precious time doc. Regards from maldives
