@migizii I’m in Bemidji, MN and perhaps you doctor at Mayo in Rochester, too? I have not entered the shower head discussion as I am not convinced it to be anymore of a problem than anything else we run into in our life. We need to be careful, but I don’t want to be overly concerned. I checked with my pulmonologist and he wasn’t worried about hot tubs as long as they are cleaned regularly, so he thought that means excluding going in people’s home hot tubs as they are less likely to be cleaned as often as commercial settings. My recent scan showed indications of NTM infection but since I rarely produce sputum, I have to start wearing one of those vests and then he is going to order new sputum tests after there is some mucus production.
