what is causing blisters from the back to the middle of my tongue?
the blisters on your tongue could range from simple trauma (tongue biting and abrasions) to chemical or thermal burns (pizza) to systemic conditions caused by viruses (herpetic). a careful history and clinical examination are a must. if your family dentist has difficulty in reviewing your situation look up an oral pathologist a periodontist or oral surgeon. it is within the realm of their expertise. in general if the lesions disappear within two weeks they are benign and were caused by a transient condition such as trauma or virus. if problems and ulcers last a careful examination by a professional is needed.
