I havent heard of it before. With all the episodes of hemoptysis ive had i have never even had that suggestion by any of my doctors. In fact in all my 42 years, i have yet to be on steroids.( knock on wood)
I guess if inflammation is what is causing the hemoptysis, maybe, but thats kind of like the chicken coming before the egg theory......... Because its the infection that causes the inflammation. You can treat both, but both rarely ever really go away.
