Thanks for writing to H.C.M. for your query.
I have gone through your query and as you said that you have flu and cold along with it there is blocked both ears and throbbing headache
. You have asked weather this may kill anybody ? Our answer is never.
The disease process is as your cold had given rise to sinus infection
leading to severe headache
. THe infection from here also reached to throat and than to ear by Eustachian tube. In the ear they cause acute otitis media
which is a painfull condition and also leading to blockade of ears.
For treatment you should take antibiotic, anti inflammatory, mucolytic and decongestant. you can also take steam inhalation and warm saline gargling.
I hope this will help you.
