Hi @teresa My NP suggested this might be the issue and wants to do a pulmonary test to rule out on the 23rd. Meantime, breathing has become very difficult now regardless of the position I am sitting. They did start me on BiPap but I have stopped it as it made me suffocate and start to choke. All of my research into this possible dx points to it exactly as my symptoms are identical and I feel it was surgically caused. Thank you for your reply.
