First of all, I used the search function and I haven't found an answer to my question.
So, let me start from the beginning.
In August 2012, I twisted my left knee. Something popped, it got swollen for about 1 week. I iced it, rested it, and it got better.
When I saw that after the swelling got down, that I had my strength back and I had no stability issues, I thought (and still hope) I hadn't torn anything.
After about 3 weeks my knee was feeling better, so I started training legs again. The whole deal: leg extension, squats, leg press, lunges, flexes, stiff legged deadlifts , in that exact order.
Everything was a ok, since two weeks ago, when I was trying to do some hanging bent knee leg raises, for lower abs, when a sharp pain struck my knee.
Today the pain is still there, but here comes the strange part.
If I squat (body weight), or if I sit on my tibia, or if I just sit in a squating position, IT DOESN'T HURT, but if I try to bring my knee to my chest, or bring my heel to my glute, I get a very sharp pain in the exterior front side of my knee. The pain lasts for about 15 seconds and it goes away, until I flex my leg again.
Yesterday I was training back, and when doing my last set of Pull Ups I bent my knee (without thinking), so I can get one more rep, I lost my grip and almost fell on my face.
I am going to see a doctor next friday, but until then, does anyone have any ideas what that pain is about?
It's freaking me out.
