My apologies for not being able to answer your specific questions. Unfortunately, I do not live with CF, so I'm unable to speak to what it's like. I want to help get you some insight and support so you can figure out what you are experiencing. Can you share more about the doctor you have seen/spoken with? In my time moderating with Health Union, I have encountered many community members who have had to step up and be their best advocate by getting second, third, and sometimes fourth or fifth opinions to find the "right" doctor to jump on their care team. It's no easy task, but you deserve the answers and support. Sending you positive thoughts & vibes. -Beth (Team Member)
