My ears were feeling stuffy but stopped after 2 or 3 days but there is still a little pain. What should I do?

Swimmer's ear. Swimmer'?s ear ( Otitis externa) is a painful condition resulting from inflammation, irritation, or infection. These symptoms often occur after water gets trapped in your ear, with subsequent spread of bacteria or fungal organisms. Treatment includes careful cleaning of the ear canal and use of eardrops that inhibit bacterial or fungal growth and reduce inflammation. See your doctor.
