Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems that due to infection causing bronchitis
as well as cough
and phlegm formation and post nasal drip
there has been infection and fluid accumulation behind the ear drum that is leading to clogged feeling in ear..
The medications advised to you are appropriate and you can continue with the same for the advised time duration..
You can also take decongestant nasal drops containing Xylometazoline
as it can help in unclogging the ear..
In case if it still does not open up get an Otoscopic examination done and in case if there is fluid accumulation manual drainage
can be established to relieve the infection and also unclog the ear..
Avoid excessive water exposure to ear..
Do not pick the ear with q-tip as deeper penetration can damage ear drum..
Do not try to pop and unclog the ear as it can also cause perforation of ear drum if excessive pressure is applied accidentally..
Hope this information helps..
Thanks and regards.
