The body aches could mean too much fluid removal. Some people cramp all over, rather than just feet and legs. My hand on the fistula arm hurts sometimes when I wake up. My docs think I have some nerve damage from my 3 fistula surgeries. I don't have any pain while on dialysis, and was told by my center to let them know if I do. I think they said it could be a sign that I have a narrowing of my fistula and they would refer me to the access center for evaluation. My younger brother developed neuropathy while on D, and was prescribed neurotin sp? for the pain. He said it felt like pins and needles in his hands and feet. It really bothered him without the meds. Not sure if that is a common side effect of dialysis and kidney failure or not. So sorry I am not more help! Keep pushing for answers until you find some relief. A lot of times the docs don't pay much attention to pain issues. Hope you get it figured out. Maybe google neuropathy and see if the symptoms sound like what you are feeling. Good luck!
nsdq, you need to be very careful about taking supplements unless your doctor know that you are doing so, particularly ones that contain magnesium, which can build up very quickly. the same with taking calcium. Unless it is prescribed, taking calcium can lead to a high calcium level and calcium deposition insoft tissues and blood vessels. You need to be very careful about self-diagnosis and self-medicating. how do you know that the muscle and finger cramps are not related to kidney failure or a side effect of it?
Besides, one-to-three, small-to-medium-sized pieces of dates once daily won't hurt: dates is rich of nutrition and minerals (refer to http://www.livestrong.com/health and see yourself about the *health benefits of dates*).--nsdq
