Tickling Sensation in My Ear?

It seems like I'm like a few others that are having a tickling sensation at the opening of their ear. It feels as if there's baby hair in there just continually moving all the time which creates a tickling sensation and sometimes a numb or tingling sensation. Is there any possibility to tell me what's wrong? Will I end up having a fungus in that ear? I am also using ciprodex ear drops. I was actually prescribed those ear drops for my left ear because my eustachian tube kept collapsing and I couldn't hear. When I blew air through my ears holding your nose as we all know that did the trick. It would pop my ears and I could hear for a second and then it would collapse again. I also heard from that ENT doctor that I had a retraction compartment. I let him see my ear with my nose closed and blowing popping my ears that way he can see if maybe there's something going on in the place where he couldn't get through when it was closed and that's when he said I had a retraction compartment. It was wrong which is BS. I don't know any ideas.
