Well to my perspective, I have gotten swimmer's ear & an ear infection. They both have the same solutions:
Solution 1: Go to your local doctor, schedule an expensive appointment and get a prescription
Solution 2: Make an ingredient mixture medicine with vinigar & water.
Solution 3: Find an old swimmer's ear prescription and use it as directed on medicine bottle.
