My mother was brushing her tongue a couple of days ago and it began to bleed.  Upon closer inspection, she noticed a raised red patch on the center of her tongue that looks like a piece of dough.  She says it doesnt hurt and has no effect on her eating.  What could this be?
Hello, thank you for consulting with Chat Doctor. This patch can be just a fibrous which might have occurred because of trauma from something, or it can be just a taste bud of tongue. Better once you visit a good dentist and get the patch properly examined, as right not there is no pain in it, but it might create any problem in the future. Hope it will help you.
