dude, dont get all in denial, it doesnt hurt that bad to completely blow your acl. been there, done that, i was in denial, first, if u heard a pop/snap, thats probably not a good sign, second is how bad is the swelling, if you've been icing for like 5 hours and your knee is still the size of a large melon thats a trouble sign also. basically what your acl does, is keep your knees from hyperextending, and if you feel like when u walk your knee wants to give out on you backwards, you are lacking some parts if not all of your acl. get it checked out and keep us posted
