Fistula process and living with it

Hi, (if admin need to move this elsewhere) but does anyone have any advice on exercises, being careful etc after having an lower arm fistula for dialysis as my procedure is now booked for next month

All a bit real now after having a falling egfr from mid high 20’s, 5 years ago, which was dropping like a stone, then stabilised for 2 years to drop again, it’s now getting to that time.

Thanks
