Any natural ways to cure chronic rhinitis?

So firstly, I survived the brain eating parasite, I’m still alive.
However, for the last 3 months – since summer, I’ve been waking up with a really blocked nose, just one, actually, it blocks up as soon as I lay down at night, sometimes it’s quite painful in the morning and I can taste blood as I swallow. The Dr put me on Doxycycline, but after a week it did very little and he told me to stop. It’s actually driving me insane.
One nose is always blocked, I have no headaches, no fever and the mucus is clear, sometimes in the morning there are specks of green but nothing huge. I am going to see an ENT but they have no appointments for another month. Not sure it’s allergies as I rarely sneeze, however I always have sore itchy eyes. What I’m asking, is does anyone else have chronic sinus issues and what do you do?
Should I go and ask the Dr for more antibiotics? I’ve tried steroid spray but it changes nothing, currently, I’m massaging my sinuses and avoiding dairy, but still miserable.
