Patient discussion about calf

Q. I have just developed a pain in my calf - feels like it clicks when I walk, and is a sharp pain I first noticed this problem this morning. As I stepped out of my car, I felt a sharp pain in my left calf, and it has gone worse as the day has gone on. No pain until I walk.

A. as i think of it- fatman's answer seems more logical. but usually people can tell the difference between strained muscle and other stuff. if it was just a pulled muscle he would have thought of it and naturally massage the area. no?
