Be careful. A few years ago I tore my meniscus and I could barely walk. It was in college right before finals so I couldn't see the doc for about 2 weeks. By the time of my appointment it felt so good that I figured I had pulled something and it had healed. I went to the doctor anyhow and turns it out it was indeed torn, pretty bad in fact. I needed surgery. Anyhow, what I'm saying if you start exercising again and feel even the slightest pain get an MRI. Best to take care of it before it gets bad enough for surgery.
