Swelling...Behind The Knee!?!

Anyone ever had swelling BEHIND the knee? It feel as though my calf stops me from bending down entirely in the squat.
Thank you for any help/suggestions.

I’ve got the same problem. I think that mine is maybe a very mild hyper-extention. It only happens when I sit for awhile, then it will loosen up. It comes and goes. I had it a couple of years ago and it just came back. I would also be interested to hear some therapy or solutions to this same problem.

A friend of mine has this same issue. He was told he has a Baker’s cyst on the back of his knee. Might be something to get checked out.
