Pressure

[Philo13]

Whenever I dive to a depth of around 6ft underwater, I get a sharp pain in my head behind my right eye in particular. This is very frustrating (as well as painful) as I am capapble of diving alot deeper but am being held back by this. I assume that this is something to do with the increased pressure but have no idea how to correct it. Any help much appreciated!!!!
Cheers

pinch your nose and blow

This is a common, though not universal, symptom of pressure imbalance. Most people feel it strongest behind the ears, but the sinus passageway does go behind the eye. Some people feel the pressure more there, but the problem is the same, Sinus cavity doesn't match outside pressure.

Holding your nose and blowing or any "ear" clearing technique will help.

Read about the Fattah-Frenzel technique.

It's called equalizing and like the above poster said, the easiest way to do it is to pinch your nose and gently blow through your nose (don't blow too hard though). That way the air can't escape from your nose and will instead go to your ears. You shouldn't feel any pain anymore. But you should equalize frequently. That equalizing technique is callled valsalva, but there are several others as well.
Many say they're having problems with valsalva (it's becoming harder to equalize as you go deeper) - so another commonly used technique is the frenzel technique, which is more complicated though. You should check out Eric Fattah's document where he explains the frenzel step by step.
