Hi, I have a hole in my left eardrum. Recently I started to hear popping and crackling in my ear like something was moving around in there. I took a course of antibiotics and the sound stopped. A few weeks later my ear ached, so I went on another course of antibiotics. I have finished my antibiotics and now have the same crackling, popping, swooshing sound again. Is there an expanation for this and a cure?
