### input:
I fell on my knee hard about 15 years ago, I was sore and in pain for two weeks, then it went away, I could jog and ride a bike, then 10 years later I was playing volley ball, the pain came back for one week, then went away. One year later I was swing dancing when my partner turn me really quick that I felt my knee pop, I was in pain for a whole week. I don t play volleyball but still dance but just careful how I turn. I continue to jog and ride a bike, until recently back in September 2012, I was perparing for a party which caused me to be on my feet for three days in row, after the party the next day, my pain came back for a couple of weeks, then went a way, then two weeks ago I was squatting for along time doing chores, it was fine, until the next day, I was in pain, I m still in pain.but I still did some bike exercise. Now it seem harder to walk, bend, sit at my desk for along period of time. The pain is all over the leg beside the knee, expecially the thigh. Do I need to go to the doctor and get an x-ray, I ve never been to the doctor about my knee. I know now not to squat, play volleyball. I dance carefully too. If the pain goes away, do I just take care of my knee more carefully. Do I just need bedrest for a week. I feel now it take longer to heal. What do I do now? Thank you.

Hello, I have read complete details. Looking at your details it looks that most probably you may have a meniscus or ligament problem. In this case only having an X-ray will be not sufficient. You should have MRI of your knee. At present, you should do following to prevent further injury:- Use a knee cap over the knee-Avoid turning on your knee. Avoid running, squatting, dancing and putting pressure over knee. Clinical examination and MRI result will further decide next course of treatment. Hope I have answered your question. Let me know if I can assist you further.
