I Poked A Hole In My Left Eardrum In December.

I poked a hole in my left eardrum in December. That healed but now my left ear and left nostril are clogged and I can barely taste food. I have a salty taste in my mouth and my tongue has a whitish color. Been to 2 ENT doctors. A couple of visits and they cant figure it out. Also I bought this thing online where it blows air into your nostril and while swallowing it opens up my ear. But only stays open for a little while and while wearing a breathrite strip and using that tool my ear will stay open for hours. Just trying to find a answer to this. Its hard living with the left side of your faced clogged up.
Thanks,
Rich
