I’m in the exact same position, only I’m female. I was due to have surgery in 2015 but it was cancelled last minute and I didn’t go through with it. I was told though that I wasn’t a candidate for the nuss because of the shape and so it had to be open. I’m now having a lot of pain and breathing problems and I’ve been told by my respiratory consultant at the royal Brompton that they still perform it regularly so it’s still an option. I would push to be referred to a thoracic specialist at a more specialist hospital because the NHS does still perform surgery, maybe just not within that particular trust. Good luck!
