I am thinking that you need to get the top end of your mask OFF the bridge of your nose or more appropriately, you need to use a mask that has some sort of support spread out over your forehead.
My first mask actually blistered my nose and made it bleed within a VERY short time and the heck of it is that I KNEW that was going to happen and had not knowledge to do anything better! Now I do thanks to all of my friends on the forum and SleepingUgly as well! This forum is a wealth of information and while you will see some friendly sparring going on I think that for the most part all are friends and are up against the same ogre.
My second mask was a ResMed nose pillow and it leaked like a sieve whenever I smooshed my nose into the pillow no matter what I did. Gone.
My third mask was a Mirage Activa LT Large/Wide and it was an epiphony for me. At last no nose blisters. Good seal. I could actually sleep on my side. Leakage varied but was generally not too bad and that is the mask that I use mostly these days, except:
I decided that I did not like the leak rate varying and saved up my pennies and bought a half dozen masks to try out in the comfort of my home over the summer. The first mask I tried out was the ResMed Quattro Pro in Large (I want it to sit on my fleshy cheeks and away from boney parts as much as possible). Whammo! Blam! Pfzzt! Bingo! Wowee! Don't know if it was just because it was the first night last night and a brand new and supple mask, etc., but I loved it. It also has a forehead support to keep pressure of the bridge of your nose and square it up for a good fit. I could hardly wait to get downstairs and plug in the data chip to see the results, despite a broken night of sleep mainly for other reasons (my rehab dietician has taken charge of my life and what goes in my mouth with the expected results of loads of fibre, veggies and a late night snack that includes carbs - the stomache and intestines are going in overtime mode all night). Anyway, the fit was the best of any mask used to date (your results may vary) and looking at the results on the computer, they are as good (pretty much) as any results that I have had with any mask to date. In fact, the leak rate was virtually nil and pretty steady which means that my rolling around in bed and smooshing into the pillow had little effect on leakage. The only pain was getting it on but I am sure that this will correct itself by the end of the week with experience as to where the straps plug into the mask. Getting the mask off in a hurry, my biggest bugaboo, was unfounded as I could get it off with one swipe of my hand in a fraction of a second. In short, I am in love. (But having said that... I am still going to try the other mask out during the summer months).
One thing that I noticed was that there was some "blech" at the bottom of the mask in the morning when I cleaned it... probably stuck my tongue out in my sleep or had my nose drip once or twice. Asides from that? Perfection. Comfy. Efficient. Inexpensive ($50 stateside online; $350 in Toronto from the stores).
So, your short answer is simply that I would try to spread the pressure that normally is on your nose bridge across your forehead with a better designed mask. I am guessing that what you have been using is what came with the CPAP machine. I have already tossed mine in the garbage.
