Pulled butt muscle. HELP?

I have been jumping on the trampoline, doing cart-wheels, running and multiple leg and butt exercises. One day, i had the pain on the muscle of one of my butt cheeks! I can't even walk without falling to the ground. Sometimes the pain is manageable and sometimes its so unbearable. I love working out, but it hurts. How long will it take to heal? Anything i can do to help it heal faster?? Thanks!
