Hello, I have been taking cipro for epididimitis and it has worked for that, but I also noticed that for a couple of days while I was taking it that it improved my breathing. It didnt last very long but it felt like I was absorbing more oxygen than normal and I wasnt as pale. I dont have any major symptoms for a lung infection, no coughing or fever. I'm 28 male avg weight, non smoker in mostly good health.
