I would think that it would clear up in a few days.
I have been certified for 25 years and never had any problems with me ears.
But , swimming with my daughter this past summer, every time I go under the water my ears are getting clogged and feel screwy for days after. I have not tried ear plugs yet, but I will in the future. You both may give this a shot to see if that helps. You guys were not that deep for that to be an issue. I have been down to 130 feet and it felt no different from 10 feet as long as you are pressurizing every 5 to 10 feet.
It's a wonderful sport! I want to go somewhere with my wife to get her certified this year.
Where we're you diving at?
I have enjoyed diving in Cozumel , Playa Del Carmen( great Cenotes!), Dominican Republic, St. Thomas , Key West, Thailand, and Hi.
Enjoy,
Todd
