I had a septum correction, tonsyllectomy and uvullectomy 5 weeks ago, after the 2 week my nose started smelling really bad, my ent doctor says that there is no infeccion and she doesnt know the cause of the bad odor. Its really annoying, I rinse 2 to 3 times a day wit the netty pot, but the smell persists. When my nose starts dripping and the smells gets worse. What can I do? Do I need a second opinion?
