Well I have no idea so will guess a spider bite/bits(or Morgellans).

No, not Morgellans - this is a true organism. It does not look like any of the tropical fly larvae I've seen, but I would have to guess that it's a maggot of some sort - ? blowfly/calliphora

Very interesting, this is clearly myiasis, but the interesting bit is that this is a third instar larvae belonging to Musca domestica; the common house fly! This is apparent due to the morphology of the spiracles, with the characteristic sinuous slits with a full, heavy sclerotized ring and obvious button. more information may be derived from the morphology of the sclerotized mouth parts in some species, but not in this case.
