Rectus femoris injury, not healing, any ideas?

I've had this injury for about seven months, my old doctor said it was the ITB/TFL, but I got an MRI and it said there was tendiopathy in the Rectus femoris. I play goalie, so this muscle's health is crucial. I cannot extend my leg, as in kicking and have a hard time bending over. This injury is pure hell, please help, I have iced it, used heat, used arnica, used ibuprofen you name it, and nothing made any long term progress.
