What is MAC? I have been having lung ever since my car accident 1 year ago. I fractured my sternum and had a collapse long. They put me on steroids and told me I had a virus. But then my lungs got woarse and they said I have Bronchiectasis. Then I had fallen walking my dog and could not walk up stairs or across the hall to my bathroom with out my oxygen dropping. I went to the ER and they said I have pneumonia, a blood clot in my right leg and UTI from stressing continence from coughing so much. Also, now I have blood in my urine but no infection. They’re checking me for autoimmune problems and say that it’s inflammation. They said it’s definitely not a virus. All the viruses came back negative. I had cancer as a child which did put some scope on my lungs, but I was told that the scarring has not changed. They’re worried that the truth I had in 2022 could have caused some of this, but my oncologist says no it’s too far out. even though I have all the symptoms except the autoimmune if you listen to the commercial, I have mucus in my chest now it’s starting to break up now that my chest fracture is starting to heal. I can actually cough and get some stuff out. I’m a lot of medication. They want the pneumonia to heal then do a bronchoscopy. But my pulmonologist does not want to put me through that when he says the treatment is the same. I just don’t know what to do but I have been like this for months. I went from do martial arts to not being able to walk across the bathroom hall without oxygen 24 hours a day. Any suggestions would be greatly appreciated.
