I am a 23 year old girl and I've never been able to breathe through my nose for as long as I can remember.

My nose has always been either blocked or runny. I am very congested and always have a tissue on hand incase I sneeze or need to blow my nose (which is often.) Its like I have a permanent slight cold. The only time my nose clears up is when I have been doing exercise and then its only clear for about 10 minutes maximum and it "blocks" again.

My parents took me to doctors when I was younger and they didn't do any tests or even look in my nose they just said "rhinitis" and prescribed steroid nasal spray, but my parents (who are kind of alternative and hippyish) were worried about me having steroids at such a young age/getting hooked on them or something.
They also took me to alternative medicine people who told me I had a lot of allergies to dust, pollen and car fumes (!)
Anyway nothing was really done to help me, and I just kind of forgot about it, I'm so used to breathing through my mouth anyway.
But now I really want to do something about it. It's annoying and embarrassing that I always snore when I sleep, and its annoying always having to carry tissues with me.

I only get hayfever about once a year for about a week. And I seem to be able to go camping and stuff fine without getting too irritated by grass or whatever. My nose seems to stay at the same level of blocked whether I'm in the city (where I live) or if I'm on holiday in the country.

But whenever I'm around really dusty things(looking through old boxes etc) I can sometimes get a really severe attack where I will be sneezing uncontrollably for about an hour, and my chest will be tight and I'll wheeze and my eyes will itch and I will feel awful.

My nose also gets especially blocked or runny or I sneeze when there is a sudden change of temperature or if I'm somewhere really cold.

The main factors that make it worse are DUST and being somewhere cold. However it is always bad. Right this minute, it is not COMPLETELY blocked...I can get a certain amount of air in, however not enough to breathe properly. I have to always breathe through my mouth.

My dad has a problem with his nose too, he is very allergic to dust and pollen, always sneezing, BUT the main difference is although he has attacks, when he is NOT having attacks he CAN actually breathe though his nose. Whereas I can't. Ever.

I want to go to the doctor but I'm worried they will just prescribe me the nasal steroids. I dont actually mind taking them, I don't have the same ideals as my parents, however I have read that the steroids are not a permanent solution, they should only be used as a temporary. However I NEED something permanent. This is not the case of sometimes having attacks this is ALL THE TIME.
Which leads me to think maybe its something more than rhinitis?? Everywhere I look online people with rhinitis only seem to have it SOMETIMES not all the time?
Has anyone experienced anything like what I have? Anyone got any ideas on how I could be helped?? I would just really love to not snore and to be able to at least SOMETIMES breathe through my mouth.
To be honest I don't even mind occasionally having attacks I would just like to be able to breathe properly the rest of the time!
It would be amazing if anyone could help! sorry this is so long, just wanted to explain everything! Thank you!
