Sooo I twisted my ankle...?

I just need some advice from people that have fallen/gotten sprains a lot or just from any professional. So I thought I would try to learn how to skateboard this summer... yeah... so I fell in some weird position and my ankle and calf have been killing me. It hurts when I walk on it but it's not impossible. I fell a couple hours ago but it just feels like as time progresses the pain is just getting worse and worse but there's no bruising or swelling so does that mean it's getting better? My mom keeps saying it's nothing but man I keep crying from pain and I'm not the kinda person that cries easily. Do I have to go to the doctor and get one of those things or should I just tough it out for a few days?
