Ear canal fungal infection?

Hi,
I thought I had already posted this but it hasn't appeared in the forum.  So here goes again.
I had a bad ear canal infection about 5 months ago (after visiting my audiologist!?!) and decided
to self treat with a 50% white vinegar solution, using a Q-tip (I know, you're not supposed to do that!).  
It worked because the infection went away.  However,
a couple of weeks later, the ear began draining again, but no odor.  I went to the doc who then prescribed
antibiotics with the advice that I should see an ENT if it did not clear up.  Well, it didn't and now I'm
waiting for my ENT appointment.  The issue is further  complicated because I wear a
hearing aid in that ear.  I will let you know how it goes, and if it is a fungus -- I'm told fungal infections are
very difficult to get rid of.
