This is behind the inside of my left knee. I just learning whirl, and have been drilling pixie. It hurts and I am worried about really screwing it up. Should I quit the whirls? Or can someone show me how to stretch it properly?
edit: by the way, I sharpied my own fucking leg and took the picture myself-which is why it looks so stupid. But I figured it'd be worth it if someone [cough]Caleb/Hood[cough] helped because it hurts walking
edit/edit: By the way, I'm stupid for sharpi-ing my own leg
At first, I thought you cut yourself or something because you used a red sharpy, haha. Anyways, that is a great idea to mark where the pain is and take a pic. Only thing that is blurry in my mind is what type of pain is it. You say it hurts, but describe how it feels. Is the pain constant, sharp, dull, a tightness, soreness, only hurts during some footbag moves, etc. etc. ? Why in the first place do you think it is your ACL, is there something that is leading you to that ?
Anyways, if it is a muscular soreness and it feels more superficial (ontop) then what you've marked is the hamstring (semimembranosus / semitendinosus). Also underneath the hamstrings are the origin of the calf (gastrocnemius- medial and lateral heads), and then some other smaller muscles that don't play such a large roll in flexing the knee. All those muscles in that area flex the knee. Skooling whirls can make that area sore easily because it is a very initial quick knee flexing movement and then a quick extending movement which makes the muscle and tendon work pretty hard by shortening and elongating really quickly. If it feels tight and needs stretched, try any type of hamstring stretch, calf stretch, and that should take care of the tightness felt behind the knee.
ACL ruptures/ tears will many times be accompanied with a pop and a lot of swelling. The ACL is located directly inbetween the knee joint attaching from the femur to tibia. After any ligamental damage will be loss of stability. Most Ruptures/ tears happen from a twisting/pivot movement or some sort of trauma that pushes the tibia (shin bone) anterior (forward).
