You were attacked by a pack of coyotes?
Coyotes are normally solitary animals, except during the mating season.
When I was living in Los Angeles, interaction with one coyote or another was a weekly occurrence, even within the city.
They don't normally attack, or menace, fully-grown humans. Small children and pets, however, are at risk.
Did you report the attack to animal-control authorities?
There may be a rabies problem involved.
