Has anyone had a pain in the back of the knee that makes doing a breaststroke kick essentially impossible? Not sure if that's how I hurt it or if it's something else. Also hurts when bending - either sitting down or getting up. It's sort of strange pain in that it doesn't feel like that part of my knee is straining at the moments when it is hurting. Suggestions for what this might be are welcome. (And yes, I will go to the doctor).
