<br>Interesting to see others experiences. I've had Myco Ab. for about 15 years. I have cavities in my lungs and have frequent alternating treatments of 9 months oral Azithromycin & Rifabutin with nebulised Amikacin & Aztreonam. I know I need treatment by the amount of blood I cough up. I also have the infection in my intestine which has caused much damage & my ascending colon had to be removed. My transverse colon is now affected but I try to manage the symptoms!
