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...
