Hi doc, so about 5-7 months ago I had strep throat along with ear infection. However when I was little I had several procedures with tubes in my ears. I m not sick or anything but it keeps happening. My right ear goes pretty much deaf where I cannot hear anything but when I plug my nose and blow (people around me can hear it to) my ear screeches very loud and it actually feels better lt releases pressure but when I stop blowing I get really dizzy the pressure goes back and my ear goes back to not being able to hear out of it.
