Greaux also suggests manual therapy or Active Release Techniques (ART), a special massage to treat injuries.

It can break up scar tissue in the hamstring and relieve pain behind the knee.

A small tear will result in minor swelling that will improve over two to three weeks.

A more moderate tear is the bang out that causes pain in your knee when bending.

Doctors may suggest physical therapy.

If a bike seat is too high or too far back, your calf muscles are vulnerable.
