Hello and welcome to HCM,
You have mentioned that your child had a chronic ear infection
sometimes associated with wheeze, adenoidectomy
with insertion of tubes in the ear drum.
The purpose of the tubes is easy drainage
of the secretions in the ear.
Since, the ear and throat are connected by eustachian tube, any collection in the throat (due to infection) will enter the ear cavity.
Thus, the tube will drain all the collections in the throat and in the ear cavity.
Now, the fresh complaint is that of some foreign body sensation in the ear.
This could be due to the displacement of the tube.
Infection will cause associated pain and discharge also.
So, you need to visit your ENT specialist
for examination of the tubes.
Thanks and take care.
Dr Shailja P Wahal
