It seems that the pool that your son swims is not being kept up to adequate hygienic standards as he has had a recurrence of severe swimmers ear. Your son should be treated again with Sofradex drops and may need an antibiotic by mouth again. He should be seen by the eNT again as I am concerned that he may develop a chronic form of this problem and he is oin such pain. You are doing the correct things to prevent a recurrence but should insist that the pool water be properly treated.
