Hi thanks for posting your query.
Discharge through both eyes and left ear following common cold
are complications ,which result from flue.
The flue has resulted in otits media that is infection of middle ear due to which your ear drum has ruptured resulting in discharge through your ear.
The discharge through both eyes is due to blockage of naso lacrimal ducts ( ducts which drains tear from eyes into nose).
The decreased hearing is due to ruptured ear drum.
your advised to consult an ENT surgeon who will advice you regarding the management of perforated drum and blocked nasolacrimal duct
Hope I answered your question.
