Otitis externa: An ear canal can become irritated by vigorous cleaning, prolonged exposure to moisture, and infection. If the irritation is new, apply a solution of 50% hydrogen peroxide to the ear canal while laying on your side. If the irritation lasts longer than 1 week, see your GP as you may have a bacterial or fungal infection or allergic inflammation which need to be treated with prescription meds
