Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain leaking ear with gooey discharge are indications of
ear infection and as he has a recent history of
cold, many a times cold leads to progression of infection in ear as throat and ears are connected via Eustachian tubes..
I would suggest you to consult an Paediatrician or an ENT expert and get evaluated and a thorough clinical evaluation and investigations like otoscopy, can help in diagnosis..
He can be advised antibiotic and
analgesic ear drops for reducing infection..
In case if still the discharge does not stop, at times manual
drainage of ears along with placement of pressure equalization tubes can help..
Hope this information helps..
Thanks and regards.
