What causes severe pain in left knee behind the kneecap?
I fractured my right ankle playing volleyball about 6 years ago. I had a surgery following the injury due to scar tissue on top of same ankle. Six years later, I have severe pain in left knee behind the knee cap on back of my leg because of favoring the right ankle. I never felt like the arch healed properly. I don t know what else I need to do. I have gained weight because both legs hurt by end of my workday. I m a teacher. I no longer am able to play sports and just want answers!
