It just seems strange to say the least. The worms that are pushed out of your nose are they alive. Can you see them moving?? I really don't know what it is. Also, 2 weeks after the cleanse is really a long time after the cleanse for things to start showing up.
You could start experimenting with putting small amounts of oils and herbs on your nose to see if anythign happens. Coconut oil, lemon juice, garlic water, Black-Walnut tincture, any of those seem like they would effect small parasites. The fact that they are only localized in your nose is another very wierd thing too. Also, think about your diet changes and this being related somehow to possibly a detox reaction of something related to intestinal health. It seems strange.
