I have a plugged ear after I did my first time dive 2 days ago? I have hard time to hear on that ear. It was my certification dive to be a certified scuba diver last weekend. So actually, I did 4 dives in 2 days last weekend. Since then, my left ear is plugged. It started after the very first dive, gotten worse gradually during subsequent dives. I was hoping that it would get better, but it is not getting better. I did equalize repeatedly during the dives. Some of them may be forceful, my nose did bleed 2x during them
