G'day Jay,
On 03 August 1995 you were in deep conversation with Stan Dean
 JH> If it hurts on the way down, it's probably sinus squeeze.  If it hurts 
n
 JH> the ascent, then you have a reverse block.
 JH> There is no excuse for mask squeeze among scuba divers.  That's why your
 JH> nose is inside the mask.... to allow you to equalize the pressure inside
 JH> the mask with the ambient environment.
 JH> In your case, you may benefit from the intelligent use of 
tihistamines.
I would not recommend anyone dive with a cold or sinus problems, the
antihistamines may work well on the surface, but there is the good chance
that they will wear off quickly especially at depth. Asending with all
your passages full of mucus trapped compresses air, is not all that fun. :)
