I've noticed that there is a long vein that has appeared on the sides of my tongue and follows the color of the tongue itself. It's weird because I have a canker ulcer on the side of my tongue probably from biting or something from a few days back. It seems to be healing up but noticed a vein appearing on the sides near the location near the sore. Are these two related and is it normal to get flesh colored veins on the sides of tongue? Is this something I should be worried about? Thank you.
