Oh, I’m sorry I just saw this. Of course this is just my personal opinion- my valves were placed to help a pneumothorax to heal- then they were removed. (ILD from juvenile scleroderma) I experienced so much pain/inflammation “true inflammatory response” after the valves were placed. My pulmonologist and Rheumatologist really couldn’t figure out why my body reacted the way it did. The valves did their job- my lung did heal and the pain resolved after a error and trial of many different medications/therapies. So in the end all worked out. Also my use for the valves was different then most. I would just try other options first.
