i had acl reconstruction surgery 5months ago and i feel like i am doing better, but i am still in some pain.
1)if i sit for longer than 5 minutes, i cannot straighten my leg and it is really stiff. I have to use my hands to push on my knee to stretch it. Does anyone else have this proble?
2)Also, i have a nail in my shin(where my new ACL is attached to) and whenever i kick and hold my leg backwards, it feels like something is pushing on the nail. is this normal? 3) sometimes after physcial therapy, but mostly at night, i feel almost like a pinching sensation on the outside of my knee. It does it at random times. Any reasons for this?
4) and lastly, whenever i straighten my leg really hard, the outside of my knee gets really stiff, just along the left side of my left knee..any reasons for this too?

thanks for the help!
