Is there anything I can do that will help out with the condition I get as I rise to the surface after diving. My mask is only as tight as it needs to be to keep water from flowing in and I equallize the pressure in the mask by expelling from my nose every other breath as I descend. Yet, for the most part I always have a mask of blood coming from my sinuses when I get to the surface. No pain is associated with it and it feels like drainage. A quick blow of the nose clears it out. And generally, it gets better(?) the more I dive in one day. The first dive is usually messy while the second and third are much less.
