Thanks for your question
History seems that you might be suffering from presbyacusis I.e. hearing loss
due to aging process.
Recent history of cold
may precipitate the underlying presbyacusis.
Now just take antihistamines like levocet to solve the rhinitis
Take neuro protective like tab gabaxone for a month
If your daily routine is disturbing due to hearing loss then you need proper hearing aid
Thanks, take care.
