It’s not malpractice! First - it is fairly rare and not many doctors have ever treated anyone with it. Second - those who are knowledgeable don’t want to tell their patient it is not curable. Many people have a difficult time accepting that while MAC won’t cause their death they will die with it. Azithromycin is the drug that will affect your hearing so being a musician you may want to talk to your doctor to see if you want to take it or for how long. My error was not looking up the side effects for all three when they first prescribed them - but back then I thought I would be on them for a given period and then I would be cured.
