I have a question. I am stage 4 colon cancer with met to lung and aorta ureters. After my first treatment I went into antiphalatic shock. I now take steriods before and after my treatments. MY QUESTION. After every treatment, I bleed through my kidneys, I dont mean pink tinge, I mean blood and lots of it. I will drop 2-3 grams in HgB. Has anyone else had this problem? I am beginning to think, I am having allergic reactions after each of my treaments but the steriods are helping to keep the signs at a minimum. I guess my nex trip is to my nephrologist to ask if this is damaging my kidneys. Thanks for any inof/
