Also, sometimes you can go back up...my PFT's fluctuate a lot. I mean they dont usually go higher than a certain point anymore and yes I can notice when they are going down. I dont exactly remember when my lungs started to get involved, I had lots of nasal problems before. I know that my fist hospitalization for my lung related problems was around middle school, and I was able to play field hockey in high school. I have never been a good runner tho, so to use that to gauge when my lungs became involved wouldnt be accurate. A few years ago, when I was diagnosed with MRSA, i had begun to think that decline was just something normal for me. I didnt realize how sick I was (because I had felt that way for so long, I couldnt remember feeling well) until after the IV's. Once I got the IV meds and finally treated the MRSA, I felt like a whole new person. Its so odd, how things can be so different from one CFer to the next.
Also like someone said, it could be related to other things in the environment too. For example, I dont do well in humid weather. I do much better during the winter months because the air is usually drier. Some patients would say the other way around though. Cheer up and hopefully these posts will make you feel better! <img src="i/expressions/face-icon-small-smile.gif" border="0">
