5 months post wisdom extraction discharge

I had a large cyst removed from my jaw and also the wisdom tooth that caused it. From the day of the surgery there has always been a discharge, but gradually the amount has reduced. However there is still some discharge occurring now at 5 months post op. Is this an infection?

I had it done by public health care(free) so they want you in and out as fast as possible. The person I saw(not my surgeon) said everything looked fine and said the discharge is unlikely to be an infection but didn't really give me an answer. What the hell else could discharge be, it doesnt taste like food, its salty and even if I rinse out the area thoroughly there is still some discharge taste seeping from the hole.
