@mayoconnectuser1 I forgot to mention when my spine surgeon prescribed Mupirocin as a preventative for staff infections prior to surgery, the instructions were to use a pea sized glob in each nostril 2 times a day.

This antibacterial does immediately clear up a chest infection when I get them which usually starts in my sinuses. I have allergies and asthma, so this can be a frequent issue. I also have a physical issue with lesser rib expansion on one side which tends to trap phlegm leading to an infection. When I’m not breathing well and my resting pulse goes up and usually with a bit of blood in my nose and irritated throat , I know I am getting into trouble. I discussed this with my doctor and he gives me a prescription for this as needed. It really works and gets me breathing better in a day or 2. There can also be a die off of bacteria that will cause a flushing of phlegm a day after starting to dose this if it is a bad infection.
