Talk to General Physician on Chronic Rhinitis

Assalam o Alaikum, I'm having runny nose with sneezes for around 2-3months. Initially it was only continuous sneezing randomly any time of day, specially in morning and sometimes runny nose as well. But in the last month my rhinitis has worsened, it gets better when I sleep, and worsens with sneezing the moment I get up in morning. the mucus is yellow-greenish sometimes, but mostly its clear. I also experience pain on snorting on left side of nasal septum, and crusting also occurs on left septum only. I went to clinic last month, the doctor prescribed antibiotic (sorry i dont remember exact drug, it was some cephalosporin class, maybe cefipime, but i'm not sure), upon taking which my symptoms disappeared completely, but came back after 9-10 days. I dont have any other symptom, throat is fine, no congestion and no history of allergy. The symptoms are really confusing and I also don't want to keep taking antibiotics. I have tried soften and arinac and they didn't work. Please suggest w
