It could be warts ?
Hi I think it normal. I would check with doc. To make sure
Your tongue is covered in bumps called papillae. ... For example, if the papillae at the back of your throat are irritated due to a cold or throat infection, they will become larger and red. These bumps may also be formed due to stress and food irritations. Red bumps can also be caused by trauma to the back of your tongue.
