I'm 19 and recently got on oxygen supply, in January this year I was doing fine walking around and doing house work was not too much but past few weeks suddenly it became worse, and it turns out my oxygen saturation was low even tho it had never been before. Idk how to prevent my situation from getting worse, Dr appointed me some oral antibiotics as of now. Are there specific exercises and supplements to prevent this from getting worse. I've been able to be independent as my friends and siblings my whole life uptil now despite my CF being on the bad side since birth. And I have no idea wat to do now. I also don't have access to CF modulator and dont qualify for one.
