My bro in law suffered with this disease for 1 year+, not sure how long since it originated from another lung problem called Wegeners Disease. His was, most likely, brought on by the heavy doses of meds to control the Wegeners. He was was told that 1% get PM from the steriods etc. He was one of the 1%ers. He did not recover however there are some real possibilities that might help. There is a clinic in Utah has helped those with PM. If you are interested let me know. God Bless and hang in there, Ed
