I have always been interested in diving so I am finally going to do, but I am doubting it. I am signed up for classes next month and was hoping to to my open water dives in Mexico. To make a long story short I decided to go to a pool and work on equalization of my ears, I think I went to the 12 ft depth to quick feeling pain then plugged my nose and blew to hard. Feeling the pain I surfaced and could hear the pressure in my ears. Upon going to my docter he stated there was no damage but that I had scar tissue probably from ear infections when I was a kid. Is it harder to equalizing your ears while you are desending without scuba equipment? And since I have never really equalized my ears before what should it feel like practicing at home. Thank You for your patience in reading this.
