Hi GH,I can't speak to the LINX, but I can tell you that my lung problems took about two and a half months to resolve after my NF. The damage done didn't occur in 52 days, and the recovery from that damage will take time as well. Don't give up hope that the lungs will heal given some more time. Mine healed and have done great.
Of course it is always possible that some residual damage will remain, which would be understandable. However, I can tell you that my lungs have been 100% better since my surgery. Hopefully yours will be, too. Just give them more time.
Best wishes,
Denise
