Thanks for writing to H.C.M. for your query
I have gone through your query regarding blockade in ears which developed in the consequence of you cold
. During cold nasal discharge is going back to throat and thus your throat becomes sore and here in the lateral wall of throat lies the opening of eustachian tube, which gets blocked and thus ventillation of middle ear suffers which ultimately give rise to blockade in ear.
To treat this you should take-
(a) Anti allergic like cetrizine
(c) Steam inhalation.
I hope this will help you .
