While I'm well aware that others do, I wouldn't and have not ever ridden a fixed gear bike on a hill. Unless you count the times I had to ride them when my shifter cable had broken.
If you have to strain and use muscle to pedal your bike, then at some point in your life you will have knee pains that are more than just brief pains. Which apparently yours is more than just brief pain.
