Before we dig into what may be the cause of your nose sores, we have to understand what they are. As it turns out, there are two different types of nose sores that can result from CPAP therapy.
They are nasal passage dryness and exterior sores and red marks that appear on the bridge of the nose or around the face. Typically, nasal masks are the main culprit, which makes sense when you look at their design and function. However, some CPAP users can develop nose sores from using full face masks as well.
