I'm not new to dialysis, I have been on it for many years. but you should definitely tell you doctor & nurse as how you are feeling.
I know I have had issues in the past where they removed to much fluid & made me feel that way & I have also had it where they had me on a special bath & it removed to much calcium which makes you feel really crappy & that makes your tongue & face very tingly/pins & needles. So definitely tell you doctor
Good Luck & God Bless !
