hello my name is Rick. I am studying Marine biology and need to learn to dive. On my first dive I had middle ear squeeze at 5 ft. the instuctor said "if you feel any pain don't go deeper". So I was very slow going down, and only managed to go to 12ft after 20 minutes of clearing, so slow the instructor said I would have been left behind had I not been the only student on the dive. I didn't have any sinus problem that day. My ears were plugged for days after the dive and I only got relief on the plane at 30000 feet. Are there any medical options for me like drops before diving or operation? I would really love to be able to dive.
