Knee injury advice

[TomsSVX]

Well I went snowboarding for the first time in 3-4 years today. Had an awsome time and I loved being back on the mountain. Got on my bard and tore up the slopes like I had being doing it all season. Got two runs in before I hit the terrain park. Got comfy riding the park and began to hit some jumps. At the bottom of a high speed jump some jackhole was sitting right infront of my landing. Needless to say I did everything I could to land and then try to avoid him. I did a good job and major injuries on both parts were avoided but I messed up my left knee pretty good. Twisted it in a way it didn't want to go. It hurt for a few seconds and I continued riding for the rest of the night. Problem is, now I have a severe limp as it hurts like an SOB now. Cannot really ask nurse moma for advice as I was "in class" today. Anyway, anyone here a little medicall savy and help me out with getting this healed up or should I just tough it out??
