I've been getting blood blisters in my mouth (and other places) as a result of food (or things in food) that I've eaten. This has been happening since probably about 2006. I'm 33.
I first noticed that I got the blood blisters in my mouth when I ate things with BHT (and/or BHA) in them (like cereal and gum).
I then noticed I got them when I ate burnt food (like burnt pancakes or toast). I got the blood blisters on my cheeks (inside my mouth), primarily. I got them on my tongue a couple times, but they were very small, then, although they were only painful when on my tongue, interestingly.
However, I began to notice that I would get these blood blisters on my legs, too. Oats and papaya enzymes also brought these on.
I haven't been having them much in a long time, however (but I don't eat the things that bring them on much, except oat-free cereal). I prefer corn-based cereals most, now. Frosted shredded wheat definitely brought them on (the bagged Malt o meal kind—I don't think I ever got it from raisin bran). I did get one recently on my right big toe, however. That was weird. I actually took a picture of it.
Might I reiterate that these were all painless blood blisters (except the small ones on my tongue). They weren't the sort that when you pop it really hurts and feels like the skin is burning.
I also note that I have felt them appear. They don't take time to form. They pop up instantly (without friction), as soon as whatever food it is touches that part of my mouth. It's quite interesting.
Someone once said they heard that salt had something to do with it. I did shower with salt water, and I do brush my teeth with salt water. Maybe that has something to do with it. I don't shower with salt water anymore, though (but I had these issues before I did any of that).
It's not as obvious that the blood blisters on my legs are blood blisters. They sometimes just look like red spots, like a mix between a zit and a bruise. Actually, I guess those ones hurt a little bit, or feel a little tender, but it's pretty obvious they weren't caused by friction. The one on my toe was more like the ones on my cheeks. I'd get them on the undersides of my tongue, too (those didn't really hurt, but the ones on my tastebuds were the ones that hurt).
I seem to have issues when I eat certain things. So, I was thinking maybe it's because of some kind of weird food intolerance.
I haven't met anyone else with this problem, and I didn't know anyone else had it until today. It worried me because I never knew where or when these things would appear. They seemed to be appearing in new places. Sometimes they were kind of big, and sometimes they were puny.
