Your doctor or the other commenters can help you with most questions... I was able to get my fistula shower-wet on Day 3 but you should have instructions from your doctor.For the cold, this is time for heating pads and hot water bottles! I have a bag filled with rice that I heat up in the microwave and it's so nice and reassuring. I am always cold and I sleep with a comforter even in the summer. If you can, treat yourself to a nice fluffy down comforter so you can be comfortable. I keep an inexpensive twin-size one from IKEA on my bed and it's the perfect size for cuddling in. (I am thinking of getting a second one for in-center dialysis and toting it back and forth. I get so cold during the sessions!)

Ask to have your blood returned warmer, heavier blanket (I have brought a comforter) and all else fails if your center does not have heated chairs bring a heating pad and a thermos of hot coffe or tea.
