a few months back, I had a pimple, or cyst show up on the edge of my ear canal. It swelled up badly popped and healed. However, ever since then, for some time now my ear has been feeling as if it is plugged. I can hear fine, but now it has started thumping inside and it s driving me crazy. It seems as if it s twitching inside or something. I am an audio engineer so it worries me tremendously...
