Before a hearing aid
is fitted in an ear..its important that the ear canal
should be patent..
so it should be ensured that there is no impacted wax or fungal debris or dead skin debris in the ear...The technician referred her to the doctor to ensure that this debris that he could see was cleared.As per your description it could b a mixture of wax and some fungal infection
in her ear...USe solliwax ear drops three drops four times a day so that this debris softens and then take her to the ear specialist so that it can b easily removed by him , with less pain.Once the ear canal is clear...hearing aids
can be fitted
