Has anyone traveled with pneumonitis??

Nicole
I could use some advice and words of comfort to provide me some peace of mine as I travel almost 4500 miles away from home to visit my boyfriend in Hawaii. I was diagnosed with chemical pneumonitis from being exposed to bleach. I am on steroids and I am feeling much better but I can feel the vibrations in my cough. I'm sure I'm fine to travel but would appreciate some peace of mind. 
Thanks!
