I'm so sorry you got hurt!!
I hate to tell you this, but I was front tumbling and landed on a straight leg and it tore my ACL, MCL, and meniscus... I was out 6 months.
I don't know how badly you hurt your knee but I'm very glad you are getting someone to look at it. If they don't find anything and it still hurts, I suggest getting an MRI to just be on the safe side. It honestly could be nothing but it's good to make sure.
If you have any questions just feel free to ask. I am wondering though... Does it feel lose or unstable when you walk and how did it feel when you hurt it?
