alanf, are you really contending that a North American doctor is incapable of treating an accumulation of earwax without resorting to pills or surgery? Because unless you are making that contention, everything else you are arguing is a red herring that doesn't seem to have any place in this thread.
Having been treated on several occasions by North American doctors for an accumulation of earwax, I can assure you that they offered options short of surgery, and managed to treat the issue effectively without it resulting in any disease or festering wounds.
