Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain congestion in ear along with crackling sound and popping can be due to a common cause like
Eustachian tube dysfunction and clogging can be due to fluid accumulation in the Eustachian tubes and middle ear..
As you have got ear tubes at the age of forty, there is a possibility that there has been fall of the ear tubes and there is repeated infection and fluid accumulation in the ear..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like Otoscopy can help in diagnosis and treatment can be done accordingly..
You can be advised to take a course of antibiotics, anti-inflammatory painkiller like
Ibuprofen, anti allergics like Levocetrizine and decongestants oral as well as
nasal spray can help..
In case if there is no resolution surgical
drainage of ears and replacement of ear tubes is to b done for relief..
Hope this information helps..
Thanks and regards.
