Can anyone on PD dialysis tell my what causes such horrible pain in the hip on a drain and what might help. My daughter gets such awful pain in the hip on some drains. She on a cycler, does one exchange in the afternoon and goes to pause and back on at 8 pm for another 10 hrs. The pain does occur with every drain, but often enough. OH MY HIP she will yell, and it's usually at the end of a drain, today she cried. It broke my heart. Thanks for any input.
