I had knee surgery 2/4/15 for torn cartilage. After two and a half weeks of PT, the knee was improving well. Then I slipped on ice. Another doc appointment, and according to the doc, I "strained" it. My next PT appointment, my therapist said there's something else wrong in there and told me to go back to my doc because of the snapping and popping in the joint accompanied with pain. Another trip to the doc, an x-ray, denied more PT and set up another appointment in two months. Now I'm still having intense sharp pain on occasion when walking, at times reverting to using my crutches. Am I expecting too much too soon and give it more time, or go see another doc? Suggestions please. I've been dealing with this since the second week of December and it's getting old.
