it appears that his medical provider wasn't sure either since he treated him for otitis externa ("swimmer's ear) and an oral antibiotic most likely for a middle ear infection. both these types can cause a purulent drainage and a painful middle ear infection can cause the eardrum to rupture. unless the debris/pus in the ear canal is removed one cannot really determine the source of the drainage. most primary care medical providers do not have the suction device needed to clean out this canal so they tend to "shotgun" the treatment plan in hopes that one or both will work. when the ear canal is plugged up with this gunk the drops will rarely penetrate enough to do anything but use both the drops and the oral antibiotic (not sure what he is taking however) as the medical provider ordered and this drainage should eventually stop. if it does not and your son is still having a painful ear an ent may need to examine him.
