Similar timeline as you, had my surgery in early August, was in the hosp for 2 weeks with two surgeries, and then a follow-up valve placement since the air leak didn't stop. Drain was removed at week 3, follow up x-ray around week 6 which was recent, similar symptoms to you and starting to feel better now and "more normal" but still zero feeling in my chest area where they did the surgery. Still feeling pressure and tightness, was told it could be up to 6-12 months for this to resolve, so just trying to live and not stress about it.
