Why the back of my knees hurt me?

[Finnegan Bell]

I feel a little cracking when I walk,run,deadlift at the back of my left knee

i am 95% sure it is from this exercise
Lever Lying Leg Curl


I like it very much,I lift really heavy and it makes my hamstrings swole,so an advice to lower the weights wont count as an advice! coz i wont make gains anymore!

so can I get injured from lifting heavy in this exercise?Why does my knees hurt?

i have the same thing...my pain is behind my left knee (not behind the kneecap but behind the knee).

squats-deads-running-etc all seem to make it worse.

i have a buddy who is a chiro and he seems to be able to fix it up for a week at a time...then it is bad again.

search 'baker's cyst' and see if this sounds like your issue.

why not switch to another ham exercise that is less stressful to the knees?

From my experience sound slike a the menicus ligament is strained. Mine was torn but i felt the same pain you are talking about. Get it checked out b4 you really tear it.

Also could be muscles pulling to tight.
