Im pre-dialysis , but would like to know what about cramps when you get home.? Do you have them after you are off your dialysis machine? I have been reading they will rub them out for you while in treatment. The reason Im so concerned is I get them pretty bad now, I may have one for 10 minutes. That is a long time to have one go on and on and on . If Im doing it now , will it be worse when I am on dialysis? Thanks in advance for any help on this matter.
