When you ask ‘limit in treatment’ are you referring to how many times they put me on prednisone? It was mentioned by my oncologist at one time that I might be on it for a longer period. Keeping my fingers crossed that the way my pulmonologist is tapering me off by 1mg every month and adding clarithromycin is going to do it. Before I was tapering down every week by 2.5mg and when I get to 5, inflammation comes back. I had 15courses of radiation over 3weeks period. They think mine was a result of the chemo I was on at the time as it had 2% chance of to cause pneumonitis.
