Hamstring Tendonitis?

I have what feels like tendonitis on the outer hamstring muscle where it connects to the condyle on the outside (lateral) rear of my right knee. Anyone know what would cause this?

I am thinking that the whole leg is either rotated too far out or too far in and thus I need to strengthen the adductors or the abductors of that leg. Any thoughts or advice would be greatly appreciated.

First question to ask your self what have you been doing of late that could be a possible cause??

anything new or in unusual qty./ volume that could lead to an over use problem??

does it hurt prior to and subside during?? or does it hurt worse as you go into training further?

No, nothing new, nothing unusual. Hamstring tissue quality is good too. No knots/adhesions. Vastus lateralis is also in good shape.
