Hearing to your symptoms it looks like you had a middle ear infection
, that is a condition called Acute otitis
media( AOM). Along with antibiotics and anti cold medications, you should also use nasal decongestant drops. your hearing is reduced because there must be collection of fluid in the middle ear. you can wait and observe for one more week for the symptoms to resolve. if not resolved you have to consult your doctor and get a Audiometry
done to see if the condition has progressed to un resolved otitis media or serous otitis
media, which has to be intervened.
Thankyou and wish you good health.
