What happens if the blood blisters in your mouth burst?
I once had a blood blister under my tongue on the floor of the mouth, I felt it get bigger and bigger over a few minutes until it burst. I just swallowed the blood and it stopped bleeding quite quickly. Usually they don't get very big and just sort of wither away.
That is very interesting - what was your platelet count at the time?
It was low. I only get blood blisters when I'm under 5.
So, you have had them lots of times? I have only had them once. I had one on the inside of my top lip and three on the inside of my cheeks but they did not burst.
