SORE NOSE AND TEAR DUCTS

I WAS GIVEN AN INFINITY NASAL PIECE TO TRY ABOUT THREE MONTHS AGO. I HAVE FOUND THAT MY NOSE IS VERY SORE INSIDE AND OUT PLUS MY EYES ARE DRIER. MY PRESSURE IS SET AT ONLY 7 BUT IT IS DIRECT PRESSURE INTO MY SINUS AREA. I DIDN'T FIND THIS TO BE SO MUCH OF A PROBLEM WHEN I USED MY MIRAGE MASK WITH THE AIR BEING DISPERSED. I ALSO HAVE ROSACEA WHICH SEEMS WORSE WITH THE INFINITY. DOES ANYONE ELSE HAVE THIS PROBLEM? I DO USE A HUMIDIFIER IN THE WINTER, BUT IT DOESN'T SEEM TO HELP. ANY SUGGESTIONS OR COMMENTS WOULD BE WELCOME.

Diamond Girl, I am not sure about the dry eye but my RRT gave me a product with the same contents as KY jelly to line my nose with before I used the nasal prongs. He said it would help with the dryness. I also have to keep my humidifier cranked to 3. Have you maybe developed some type of allergy? Just a thought.
