Mysterious leg injury???

Sooooo, like three weeks ago at a party(Which was hell BTW we hate parties) we decided to take our friends and go down to the lake. We were chilling on a board on some slippery rocks(Bad idea we know but we've done it before and it was fine) and our friend got on. They jumped off and when we went to get off we slipped and hit the rocks hard :[

For the last bit our leg was hurting but we thought it would be fine. Fast forward to today and we literally couldn't walk enough to get through the school day. We called Mom and she picked us up and we headed to the hospital :p

X-ray showed nothing but we had to get a boot >:[
We do not like the boot. It is stiff and feels suffocating. It is also not helping much with the leg hurts. We are hopeful it will help long run but we don't even know what's wrong yet so that's unclear

Have any other critters had to wear the boot? Did it help :[
