Hello
You have taken 5day course of azithromycin antibiotic it seems. Have you consulted ENT doctor for this,? If not please do so. The hearing problem could be because of fluid behind the ear drum for that Doctor can prescribe you decongestant tablets or Nasal drops . This fluid behind the ear takes 10 days nearly to completely get cleared. So you need to take tablets or otherwise if cannot find a doctor you could do steam inhalations , they give decongestant effect.
But I would say to consult as there are also chances of deceased hearing because of nerve problem. Which needs treatment .but chances of it seems less likely as you have problem in both ears .and nerve problem occurs more commonly in one ear only.
Your problem looks more like of fluid behind the ear due to ear infection so do steam inhalations
Next Steps
consult ENT specialist or steam inhalation
