I was able to get locally some Colloidal Silver 10ppm in a bottle with a nasal aspirator and I shot some of that up my nose twice a day. It seemed to help. I also put drops in my ear and swallowed to work it into the Eustachian tube because it felt like I had something in there too. Its all connected. It dried everything up. I am not sure it will harm you during pregnancy so be sure to check that out first.
