Hi, I had 3 spontaneous pneumothoraxes within a 12 month period in 1983. I had the pleurodesis procedure after the third episode & have had no recurrence since. I had probably fully recovered by the six week mark, but I still took it relatively easy for probably the first 3 months. I wasn't flying for a living at that stage so there was no rush to get my Class 1 medical back here in Australia...
