I fell down several steps and landed on my knee, I saw a nurse at A&E a few days after and she said its sprained, when i explained something keeps popping out of place (unfortunately it did not do this while there, so she didnt see it and I was given no x-ray) she claimed it was probably soft tissue and would go back in place shortly. Well its been 10days, all the swelling is gone, and i can bend my knee back and lay it straight but still something keeps popping out of place, mainly on the inner side of my leg but occassionally the outer as well, this happens everytime I walk. Im concerned after not being x-rayed and this long, should I go back? Is it normal, should I give it more time? Please help me!!!
