I am an avid diver 2-3 times a week and have never had this problem in the past.. I was helping with an Open Water class on Saturday and while clearing on my last dive of the day, I hearded a sqeeking noise. When I got out of the water, it felt like I had water in my ear. I used "swimmers ear" drops and suitifed with no effect. I dove to 40 ft Sunday to finish the OW class an was able to clear fine . It is now Wednesday and my ear still feels pluged. I do not have any pain, just a clogged sensation. Any ideas what is wrong?
