jenn..maybe you need an allergist or ear/nose/throat specialist.

My mom's breathing problems and allergies, nose cannula (on O2 24/7) caused her nose bleeds and dryness as well. The nose doc told her to put a very very thin coat of Neophorin in her nostrils. (I did it for her). It helped the dryness and soreness. You don't shove it all the way up, just lightly/gently a little forward up the nostril. It helped my poor mom. My brother, unfortunately, inherited her allegery/nasal problems. This weather, with the heat and dryness is wicked. I hope you feel better soon.
