Anyone know what this weird vibrating wheeze could be? Normal CT/spirometry
Hi everyone,
I’ve had a strange expiratory sound for about 3 months now and I’m trying to understand if anyone experienced something similar.
The sound only happens during maximal forced exhalation (when I breathe out very hard). It sounds like a low wheeze/buzz/vibration and I can also feel a vibration in the right side of my chest when it happens. Sometimes it can even be heard by people around me.
Important details:
normal breathing is mostly fine;
cough has improved a lot over time;
no diagnosed asthma;
spirometry was normal;
chest CT was also reported as normal;
symptoms are not clearly getting worse, but the sound persists.
I’m attaching a video/audio of the sound.
Has anyone here experienced something similar or knows what could cause this kind of expiratory noise despite normal tests?
Thank you.
