I have tried several of the c-pap masks. I have severe problems with all of them.The basic mask leaves an open sore on the bridge of my nose, even though I use the foam spacer. I have also used as many as three band aids and even made a foam cushion to no avail, I still get the sore. Ihave used the nose pillow mask, but it slips out of my nostrils at the slightest movement of my head and blows air into my eyes, waking me up repeatedly. I used the phantom mask and it rubbed the skin on my cheeks raw down to the third layer of skin. HELP! Does any one have a solution? Am I the only one having these problems ?
