I had knee surgery 3yrs ago the knee came loose the compound didn't take so I had to get a second surgery to fix it . Things was going good and then the pain just wouldn't go away the pain is in my knee with some numbness and my big toe is numb now. They did a test to see if I had a pinch nerve but found no pinch nerve in my back. So now the question is what is going on what should I do now . I've been in continues pain in my knee for 11/2 and numbness in my big toe don't know what else to do .
