ive been told by my Drs that what "coltsfan" posted are all the typical signs of rejection. im 3 months out of surgery and went thru one episode of rejection, i noticed by PFTs dipped a little, i was slightly more out of breath, and luckily i had a slight fever (yes luckily, because i knew i had to call my coordinator if i had a fever) the 3rd day and called the hospital. So i didnt feel really bad, just not 100% good, i even ran and biked the day before i was admitted with typical acute rejection, so id say listen to ur lungs and if anything doesnt feel 100% normal call your hospital......it can only help.
