Has anyone had "bacterial tracheitis", sounds and feels like croup, my doctor diagnosed it in me (severe cough, like a seal, haorseness, difficulty breathing); other MD's are saying that adults don't get croup; but this is supposidly different then croup. Has anyone had it, I want to know if it is contagious; I am worried about my granddaughter (2yrs) getting sick...anyone had this or these symptoms. thanks (there is always something new!
