It took my Dr over tons of tests for over two yrs, then I changed Drs to really great Mayo trained Internal med Dr and he fought insurance to be able to do a bronchoscope as I was finally coughing up blood . Results came back positive and had 60 days of IV Amikacin , Moxicycllin , daily with oral Clarithromycin twice daily and oral Ethambutol. I also, by that time needed monthly IVGG ( which I still get every six weeks) . During three years of misdiagnosising; everything tanked and many nodules developed . I tolerated the Ethambutol for a year but had optic nerve damage so my Eye Dr stopped it after MRI .I saw my eye Dr every two months while on Ethambutol . During the three years of suffering and finally getting a Dr to truly investigate, I yawned constantly , had to push into my lower left lobe just to get a breath and had chronic night sweats , and could only get a normal breath if I was totally flat . Extremely tired, severely depressed and lost all hope as when I went to ER they treated me like I just needed an inhaler and a psychiatrist. My CBC and other labs came back fine and I had no elevated temp. So , I know this is very long but I thank God every day for that Dr who saved me and I just want to share that if you do not have a Dr that can figure it out; keep searching and fighting for yourself with this silent destructive lung infection . I completed my antibiotic treatments in 2013 and I am doing fine now , still getting IVGG every six weeks , but just want to share my story to help others
