I went on IV antibiotics a week and half ago. I met my goal PFT in two days of being in the hospital so I was sent home to finish home iv's. I went to follow up @ doc. appointment and PFT's went down. Like even dropped more. Doc. found weezing so kept me on same antibiotics Tazcif and Tobramicin and introduced me to predisone. I feel clear in the lungs. But like I think I can tell a "brewing" starting. I'm starting to clear my throat before I speak and the hard to describe feeling of tiredness and heaviness in lung???? You know that feeling??? It will be really interesting to see what my PFTS are this Wed. a week later from when they went down and to see if this predisone stuff is working. I can take deep breathes in and I feel clear. It's not like I'm coughing up anything at all. Although, I am not currently on tobi neb or hypotonic solution. Anyone start to go uphill with IV antibiotics and then start to go down hill subtly?
