Hello doctor, I've had this nasal block in my left nostril since I had a swelling in my bone [as a fall out of an infection from an Root Canal Treatment (RCT)]. I told the dentist about it and he put me on a 5 day course of Augmenting for the second time when I told him that the blocked nose interferes with my sleep and even otherwise quite problematic. I haven't got much relief with the antibiotic prescribed. What should I do now?
