I have had that problem too! So irritating and can be painful too. I used to hold my nose and blow out, but the doc said not to do that!
Bad for the inner ear. I also have used Sudafed or any other decongestant to try to open them up. I also try to drink lots of fluids hoping to keep everything "moving". These are just my suggestions, hope one of them works. Have you tried decongestants??
