How long have you been having this?What is your age?
Swimmer's ear (also called
otitis externa) is a painful condition of the visible or outer portion of the ear and
ear canal (outer ear).
Because the condition occurs most often during the summer with exposure of the ear to water while swimming, many people call it swimmer's ear. Water from a bath or shower can trigger the condition, too.
Swimmer's ear, in general, is not an emergency.
Medical treatment includes cleaning the ear,pain killers antibiotics,pus culture if any,
Oral antibiotics are not often prescribed unless the infection is severe.I would advise you to make an appointment with an otorhinolaryngologist soon till then use OTC pain killers like
tylenol ,if not allergic
