Has anyone ever had an abscess in one of their upper teeth that has caused a plugged up stuffy feeling in their whole nose & ear area? I had a root canal done & am on antibiotics, so hopefully this will all go away soon. The feeling is similar to getting plugged up ears at high elevations. I am concerned because I am due to visit my audi for a hearing test soon (I already am severly HI), but I don’t want to do the test feeling like this. Just wondering if anyone else has experienced this.
