Ears popping and crackling is normal? I don't know how to put this properly but ever since I got my T and my doctor told me it's due to some nasal congestion and my eustachian tubes, I read up about ETD. After that every single time I swallow, yawn, burp, sometimes even move my head I can feel and hear my Eustachian Tubes open.

This doesn't exactly feel like my ears pop.. because I don't think I have pressure inside my ears all the time, but a feeling like my tubes themselves opened up. Is this normal? Does everyone hear it and I am just noticing it now because of being aware of it now? Or is there an actual problem?
