If you try CPAP therapy, you need to give it 2 weeks or more to work. You need to learn how to put the mask on correctly so it does not put pressure on your face. A healthcare provider will teach you how. The pressure in the CPAP machine can be adjusted to fit your needs. If you are having trouble with your CPAP, talk to your sleep medicine specialist or to the person that trained you how to use the CPAP. New models exist that may work better for you.
