(sorry the second to bottom line has merged with another part but the left 5th finger is mainly playing f)

It's played really fast and my problem is my left hand pinky which has to play with quite a bit of weight. I'm okay practicing this for 10 minutes a day but any more and I start to feel really worried because my finger gets quite strained.
I don't have any problems with any other part of the piece or any other pieces for that matter but this one part seems to be causing what might become an injury...
Any advice?
