It is exactly as you said Simo.
Today I could feel by pressing gently under my left eye a little soreness in the sinus cavity. I am almost positive this is the problem area.
I also recently started doing the neti pot thing. I really do not enjoy it that much and this sinus bleeding is a good reason for me to stop. Anyone want to buy a slightly used stainless netti pot?
I will take a break from diving for 2 weeks as you said, but I should still be able to to dry statics without further aggrivating the sinus tissue. Right?
