I just found out that I have mac, and I also got diagnosed with Klebsiella pneumonia at the same time, along with an intestinal cancer about 3 weeks ago. I'm not sure how long I've had the Mac for, I'm a little terrified but I wanted to tell you that I really don't have many symptoms, I'm having a little bit no problems taking deep breaths sometimes, but I also have pneumonia in there so I don't know what to think. A CT scan was done on Friday, the results aren't back yet but my doctor put in the notes on my chart tonight that the preliminary on the CT was a cavity in my lung. I'm not really sure what that means, but everything that I looked up about it it isn't good... I'm really scared about this. I don't have any other symptoms though, no coughing, no mucus even. It's just so strange. Is there anything you can tell me or advice you could give? I'm terrified!!!(
