i have this blister in my mouth for about 2 years. my doctor says it is nothing but i read it shouldnt stay for more than couple of weeks.
THIS blister keeps on enlarging then going back to a small black spot.
when i swap it, there is alway blood stains that would come out.
I also chew my tongue when i have excessive chewing my blister grow large lile in the photo then next days goes back to small dormant blister but keeps on getting blood out .
Do you like your food extremely hot? or have you damaged your tongue in any way?As you have had this for 2 years and your doctor is not worried I am thinking this is ABH or Angina Bullosa Haemorrhagica. A long name but not anything to do with your heart, nor is it life threatening.
It can last a very long time and is always identified by the blood blister appearance.,which patients often release by chewing on it when it gets large.
It can be caused by very hot food.
