What parasitic worm comes out of your but goes into wounds i have a open wound about 1 inch from my anus they come out of my anus and basically bite at my bandage tape that i'm using to cover my wound. the parasitic worm is white and about 1/2 inch?

Parasite is less likely. Fly larva is more common if you have an open wound and the wound is not clean well. Pinworm is the common parasite coming out of the anus during nighttime to lay eggs, causing irritation and itching.

This sounds like maggots or fly larvae that can sometimes invade open wounds. Wound care specialists sometimes use maggot therapy to clean up devitalized tissue from wounds.
