My follow up Chest CT scan showed that the necrotizing granuloma is less than half the size it was a month ago. Waiting to see what my pulmonary specialist says at Mayo to see if he will continue to see if resolves without antibiotics. Since my water samples of Spa/pool, drinking water and shower came back negative vPCR testing -been doing thinking of where I could have gotten this to avoid future exposure. I put down a lot of mulch this summer probably 40 bags without mask so no wondering if that was the source. Does anyone know MAC prevalence in soil vs water?
