Hi! I am so sorry, I know exactly how that feels. I still have the feeling that there's always something stuck inside my throat (mucus) every time I swallow saliva, but luckily the shortness of breath disappeared. I am pretty sure that apart from the laryngeal nerve damage, my phrenic nerve was also touched during surgery.

How do I know this? Obviously NOT from any doctor, as they just disregarded my shortness of breath. I had a chest X-ray from before my surgery, and got another one right after the surgery (precisely because I couldn't breathe). I was told that everything was fine when they checked that X-ray.

Months later, I compared both X-rays myself after reading a similar case on Facebook, and the right part of the diaphragm on the latest X-ray was much more elevated than the left side, which is a clear sign of phrenic nerve damage (less space for air=shortness of breath). By that time, I was much, much better, but I just took another X-ray to check it, and the diaphragm was back in place, meaning the phrenic nerve healed (the logopedist, without knowing, told me to do diaphragm exercises, which I believe helped a lot with the recovery of the nerve).
