Hi everyone! I had a CAT scan with IV contrast Friday. When I got home, my food tasted funny (I didn't get a metalltic taste but my urethra burned like crazy with the dye). At first, I thought it might be due to the antibiotic I'm taking for my way out of control UTI, Macrobid. I looked up the side effects and now know why my arms and hands keep getting pins and needles and go numb but no mention of metallic taste. I know it's not the Pyridiium because I've taken it before without a problem. The only other new thing put into my body was that dye. At first, I thought that maybe the company who made the stuff I ate changed the recipe but I then noticed that every food tastes funny, but it's onlly on both sides of my tongue and it's a very tart type of taste. Could it still be the IV contrast dye 24 hours later?
