Hello everyone iam new here. I have an issue with freediving casually. Previous years I used to re pressurise my ears by holding my nose in order to go deeper and deeper. I discovered the ability to do that but without holding my nose. It's like iam flexing a muscle close to my mouth and it happens. This year I can't go deep because my left ear won't represurise. Any tips on how to do it? I have a full face mask so I can't block my nose.
