Siiting on sofa last all of a sudden I had an extreme sharp right pain the side of my knee it felt like something stabbed me. It was so severe that when I stood up I was dizzy to the point ithought I was going to pass out. That severe.

This . This sounds like a possible ligament or tendon injury/rupture. You need to see your doctor right away for an examination. You will likely need an x-ray followed by an mri. Please seek care right away. Best of luck.
