I hurt my knee tumbling a few weeks ago. I landed a backhandspring, when I did my knee went inward a bit and I fell. I didn't notice a problem until a few days after it happened. My knee started popping randomly, the popping felt deep in my knee.
My symptoms now are:
*Pain on the inside, front and back of knee
*Can't straighten knee compeletely
*Crunching/Grinding feeling when bending and straightening leg
*Slight bruise to the left of kneecap
*Feels like it will give out
The pain gets so bad sometimes I could cry, and it keeps me up at night. What could be wrong? Please help.
