If you have trouble equalizing your ears while scuba diving, there are a few things you can do. First, try pinching your nose and blowing gently. This should help to equalize the pressure in your ears. If that doesn’t work, try swallowing. If you can’t equalize, ascend half a meter and try again, keep ascending until you can equalize your ears. You may also need to descend slower than usual to give your ears time to adjust to the changing pressure.
