question: My mom is a dialysis patient for over 3 or 4 yrs. I just don t like to remember;( my question is this lately her stomach has grown but she is retaining too much fluidly lately about a month ago she hurt her leg causing a sore to not heal. Just today after dialysis her leg started to throb with excruciating pain and I know it s because her legs are swollen.. She weighed in today at 69.8 and when she did her 4 hrs she was 67.4.. What is going on? Should I worry? Or is this normal.. I went to her general doctor and they said, it s part of the dialysis. I almost didn t like the answer. Even the discoloration in her legs is getting worse. I noticed her fistula sight has 2 moused sized bumps and we have had them checked. But why did they get this way and why didn t the techs prevent them from happening? What should I do?
