Pain behind knee that wiil not allow me to bend knee
I had herniated disc surgery 3 years ago, then the same disc blew out on other side so I am waiting and doing exercises and got 3 shots. Recovery has been ok but I felt really good on Friday so did some core stretches and some aerobics on a aerofit. The next moring I could not bend my right knee. There is some swelling behind knee and a little discoloation. Dont know if I have an injury there or it is coming from my back.
