Blow softly until air pressure builds in your inner ear canals. You should hear gentle popping or crackling. Descend slowly - about a foot per second. Equalize intermittently, always before the pressure grows against your outer ear. If you are still unable to equalize, ascend until the squeeze disappears, then try again.
Sinuses blocked with mucus can make equalization impossible.
Worse yet, you may successfully equalize the pressure on descent then find the passages blocked upon ascent.
