Thigh Pain Causes Pain In The Knee And Sometimes Calf And Thigh?

Pain in the knee and sometimes calf and thigh? - thigh pain causes

I am going to the gym and a lot, and lately I've had this pain in my knee, especially as sometimes the thigh and calf. If the pain caused by stress of the effort put into the knee and I tore a band, or should do more for him. The pain in my knee and that's where most of the day. Sometimes only my knees failed. Should I see the doctor and have it checked? Suggestions or comments would be great!
