Blood Blister of the Tongue
What causes a blood blister the size of a grape to form on the tongue. Five days ago while eating it appeared and kept growing till it was about the size of a grape. It was there for about ten hours then suddenly dissappeared. Then 5 days later reappeared for a minute and dissappeared. It burns really bad when this happens. It is on the bottom of my tongue. And is still very, very sore. I have had them in the past, but not this large. And they usually don`t come back that soon. Thank you
What you are describing, especially the tendency for the blister to seemingly resolve, then recur, sounds most consistent with mucocele. This is a collection of saliva or spit under the skin. (oral mucosa) This is due to a disruption or leak from the small ducts or pipes that usually bring the saliva into the mouth. A little bleeding into this spill is not unusual and makes the mucus spill look like a blood blister as you described. Additional information about mucocele will be linked to this reply.
A mucocele like the one you are describing can be a persistent problem and may require minor surgery. If the problem persists, you should see you dentist or an oral and maxillofacial surgeon for treatment.
