Get an MRI!!! It will tell you everything you need to know. An ACL tear is bad, I know i suffered one in college. However you can still walk on it. Yes you can do more damage if your not being smart. I had a tear in my acl and continued to play ball in college, I ended up causing the ACL to completely explode also causeing my TFL to get torn along with my Maniscus. Severe damage occured. I had everything just about torn out and replaced, thank god the school paid that bill.

long story short dont take chances but you can still hunt in ground blind for a short while if your careful. Know your body
