Sudden appearance of blood blisters inside the mouth may result from consuming scalding, hard, or crunchy foods, which irritate the oral mucosa. It may also be associated with hypertension or hematologic disorders. Small blood blisters in the mouth typically resolve spontaneously. However, if symptoms persist without improvement, it is advisable to consult a reputable local hospital for proper diagnosis and further treatment.
