These are symptoms that represent what is called "swimmers ear". Moisture from bathing or swimming becomes trapped in the ear canal and causes an external ear infection from bacteria or fungus. Treatment is usually antibiotics and/or hydrocortisone lotion from your physician or ENT MD.
When you bathe, use ear plugs to try to keep any water from entering your ears. Never try to dig out excess wax or dead skin, as this may injure the tissue and cause more problems. If you have ear wax build up, go to a physician and have it removed so as to prevent it from becoming lodged farther into the ear canal. Try to keep your ears clean and dry.
