Find Relief from Sinus Infections Naturally

Nasal Fungal Infection? I have had nasal issues for the past couple of years since I have had septoplasty done. Since the surgery, I have had alot of post nasal drippage and a "smell" coming from my right nostril. Now, I am self treating for systemic candida so I am almost certain this is stemming from that. I have tried using 50/50 peroxide spray, tea tree oil spray, 50/50 ACV spray etc.. and have not had luck. Does anyone have any suggestions on the best way to get rid of this? My main complaints are stuffiness (like my nasal cavity is swollen and itchy) and nasal drip (which is stinky!!) and constantly blowing nose. Sorry, don't want to gross anyone out. I'm going crazy here!!!!
