I Took A Line Drive Off My Lower Right Leg

I took a line drive off my lower right leg just above the ankle on the side of the shin. It swelled up immediately into a large bump. However it didn't hurt to bad so I played through it for the rest of the game. I iced it a bit over next couple days but did not rest it as it felt OK to walk on. About 3 days after the injury I woke up and could not walk. Now it's been a week and a half and I still can not put my foot flat on the ground with leg straight without intense pain. I've been on crutches for 5 days now. Xray came back with no breaks. Not sure if this is normal or I did something that made the injury worse?
