What are these white mites.they are in my nose and body.

Mites? : Are the "mites" moving? Have you been able to remove some & examine them on a flat surface? This should be examined by your clinician for diagnosis & treatment. If it is truly a parasite, you need treatment immediately so others won't also be infected. If it isn't a parasite, you will still find out what it is & get cleared up. Hope that helps.
