My ear is infected and I have strep. My left ear(the one with the infection felt plugged). when I yawned I noticed it helped so I tried the plug nose and blow trick. I heard a loud pop in my left ear and felt a striking pain in my ear and heard ringing. I was told doing this could rupture my eardrum. I don't know if this is true. But is plugging my nose to pop my infected ear dangerous for it?
