Surgery made breathing problems worse?

I got a septoplasty and ballon sinuplasty about 3 years ago. I don’t really remember how my breathing was when I first got it done but all I know is I never felt true relief. And 3 years later, my breathing has gotten awful, even after the surgery. My right nostril has airflow, but my nose cartilage is so softened from doing all the work and sucks in when I breathe. There is absolutely zero airflow in or out of my left nostril. I can never take a full deep breathe and I am so over living like this. I’ve been back to the doctor, tried sprays and medications to no avail. They say I cannot do the surgery again. I can’t live the rest of my life not being able to breathe and panicking every time I try to take a breath in my nose. Sleeping is miserable. Has this occurred to anyone else who has gotten surgery? This is taking a bigger toll on my life than I need. I just want to breathe.
