These are classic symptoms of a MAC infection. I read back through your posts, and saw they are awaiting results from your cultures. This takes 6 weeks or so.
The pain you mention may well be angry muscles from coughing.
Since everything seems to be progressing, your may want to call and see if there is any plan to start meds, increase nebs or other treatment to get you through until they know which antibiotics to prescribe.
Have you told the doctor your symptoms are worse?
