Replying to Knees?...

i dunno what happened...but Saturday i was trying to do this urban rail at frost and i finally slid it perfectly...but somehow on the landing i REALLY screwed up my knee..and then i did a really stupid thing and i did another rail after my fall..and i did the rail fine but i just heard a pop and collapsed on the landing and screwed up my knee even more. so now i can hardly move it and i have to limp around and crap...i have to take stairs one at a time ...ughh this sucks. plus my right knee is at least 2 times as big as my left one.

^ that was written on sunday
i went to the doc today and then i got x-rays and wed i've gotta go to some orthapedic guy who's gonna tell me i gotta get an MRI...i'm guessing next week.
this sucks so much. and when they ask me what happened i feel stupid talking about rails and stuff b/c no one knows what i'm talking about haha
the worst part is i dont know exactly what happened...all i remember is hearing a pop and then me stuffing my face into the snow and going "shit my knee!!".........and then ski patrol came and out of nowhere and tried to put down my binding from the ski that had fallen off using her hands and she couldnt it was pretty funny...but anyways
teh doc said that at a first guess it might be a tear in the cartilage...
hopefully i'll be able to ski at least once more before the end of the season...until then, i'm gonna be filming people i guess...

so when i get the MRI i guess i know if i'll be able to get back on skis this season... i'm not too optimistic....this really sucks
any advice is appreciated...
my question is should i lower my dins? my left ski popped off both times i fell but my right stayed on and i screwed up my right knee...
