Give us a  bit more info - there's bound to be a cure.  Make and model of crank, stick a picture up maybe?

I had trouble with the non drive arm on my rider coming loose - simple addition of a washer sorted it  :daumenhoch:

have you stripped it out at all?

mine used to come loose because the sleeve over the spindle (inside the BB) was too long.

probably best to get your LBS to look at it...
