Hi, went to my infectious disease Dr and he said 2 cultures ago only 1 out of 3 grew anything and it wasn't the one they were treating me for. However the latest 3 aren't growing anything. If the next 3 are negative I will start my last year on the big 3 antibiotics as long as they stay negative. Have been diagnosed since Feb 2022, on big 3 since 8/22. Keeping my fingers crossed. Have side effects but worth it if cultures finally come back negative. He said I can stop the nebulizer since it wasn't working but if cough gets worse have to start using it again.
