Purple toe?!?!?!?!?!?!?!?!?!?!?!?

so lately ive been going to the gym a lot and have been running a lot more than i usually do. one day my toes were sort of on the long side, i ran on the treadmill, so my long toe nail was hitting against my shoe and it started to hurt, i continued to work out thinking it will go away. when i got home i clipped my toe nails to relieve pain the next time i worked out. then my toe was still hurting but not to the point where it was unbearable. then i started to see my toe start to turn purple. is this a bruise? how do i get rid of this? i dont want to loose my toenail. also i want to run more because next week i have lax camp and i have soccer workouts and i want to continue going to the gym.
