I have gone through your query regarding cold

Your cold for a week had given rise to infection in your throat by post nasal drip
, from throat a tubular connection exist between throat and middle ear of that side ( Eustachian tube ). By this connection had reached to middle ear and thus your ear problem developed.
Now you may take-
(a) Tab Paracetamol
(b) Tabcetrizine (10 mg )
