Rolled Ankle Healing Time?

I was playing frisby with my family and I rolled my ankle pretty bad. I wasn't able to walk for the first 5 minutes without mild pain. I've put ice on it and have treated it with Epsom salt. I have a Parkour Jam tomorrow where I am doing a video shoot and don't know if I'm gonna be okay. It's not swollen at all, it's only the vein that is pretty swollen. I can slightly move it and walking on it is a bit difficult. Tell me what you think.
