@mary80 Oh my goodness! You are full of anxiety about this - and rightfully so. What to do? That is the 64 million dollar question. And how do you know it won’t come back? We live breathe and eat with MAC every day. Such an unwanted guest for so many! How rude! Being 44 might be a blessing in disguise as your body is better equipped to deal with it. Just maybe you are lucky! Start eating a Mediterranean diet or a plant based diet now! I spent my adult life being a grazer- and then eating off of people’s plates as a mom trying to do everything. Good nutrition and Vitamin D are key! The MAC journey is not an easy one but there is light at the end of the tunnel. Make sure you have a pulmonologist and an infectious disease doctor. Do not let MAC define you. Do the medication if necessary. Wear an N95 mask in situations where you are highly exposed like out in a field or being anywhere where there is a lot of dust. Ditch the thermal spa ( hot tub) if it is inside. Life advice - Be moderate in all things. If it turns out the meds make you sick or don’t work, try Arikayce. It is an inhaled medication (somewhat time consuming), that cured my MAC. I was shocked truly because it took over five years of on again off again oral medication. But it is gone and hasn’t come back, and that was in August of 2022. Wishing you strength and piece of mind about it. The good God has your back -,your front , your arms , your legs- all of you including your lungs!! Wishing you all good things. Just being 44 tells me you will beat this! Irene5
