Upstairs Downstairs above knee pain (Read 35 times)

Tweaked muscle/tendon just above my knee while running today. Sensation was like my knee "buckled" - bothered me for a few minutes enough to alter my stride. I walked for 5 minutes started to run again and was fine. Now I get pain there when I stand from sitting or when walking up or down steps. Looking for a gameplan on what to do?

• Ice it?
• Stretch it ?
• Rest it ? How long?
•  Compression?
  • Can I cross train for a few days - if so what - bike? elliptical?
  • What about strength exercise?

Thanks for any input.
