Tongue ulcer: You are right,injury from pressure,biting your tongue,caused the sore,but also make sure you don't have any sharp teeth,if so take care of them,these sores are painful,avoid certain foods,you will figure it out,soft non irritating diet,for pain you can apply,oragel,or lidocaine,should healed uneventfully,if looks white,it is not infection
