I have been told I have Bronchiolitis. In order to know the cause, type and treatment, I have to have a surgical minimally invasive lung biopsy under general. I also have a blood clotting disorder so not ideal to have surgery but doctor says that is they only way to know what type it is. There are a few scary types. Does anyone have this diagnosis and did you need surgery to confirm diagnosis? Also what is the treatment and have you improved or gotten worse after treatment. I appreciate any advice.
